Part 1 of Learn the lingo. Before you start shopping around, it's important to be able to understand the basic components of a turntable. Make sure that you fully understand the features and can compare the advantages and disadvantages of different brands, models, and styles of turntable. The platter rotates to spin the record, and is often covered with an anti-static felt or rubber pad on which the record will sit.

The stylus of the record player is also sometimes referred to as the "needle," and is the component of the record player that contacts the record itself. The stylus is usually housed in a cartridge, which contains the small wiring and coupling mechanism that connects the stylus to the tone arm. A tone arm can be operated manually or automatically, rotating the stylus onto the record. Good record players will have tone arms that will lift off automatically and return to place when the end of the side is finished playing. The base of the record player contains the internal circuitry and houses the various components.
Ideally, turntable bases are secured on anti-shock feet to keep the record from skipping during play.
Decide between a direct-drive and belt-driven record player. Turntables can be divided into two basic categories, in terms of the way that they're operated. For the beginner, the difference may be minuscule, but it's important to understand the different machine-styles, depending on the way you intend to use your turntable. Direct-drive turntables offer consistent machine-operated speeds that will never need adjusted, and allow dual-directional rotation.
Belt-driven turntables isolate the motor to one side of the machine, rotating the platter with an elastic belt. While the belt has a tendency to wear out over time in old turntables, the distance of the motor from the tone arm cuts down on incidental operating noise, making these models whisper-quiet. Decide what kind of features you want. Some turntables are basically a platter and a needle, with few frills or other features. Lots of modern turntables, however, come with a variety of different features that can make a unit more desirable and convenient.
Most turntables should come with a variety of playback speeds, measured by revolutions-per-minute RPM. Old shellac and acetate discs made pre are usually played at. If you want to play all kinds of records, you'll need to make sure the unit features all these playback speeds. If you've got a big collections of vinyl you want to digitize, these are essential. Tone-arm cueing systems are available in manual and automatic varieties. Some record players are operated by sliding a switch or pressing a button, which activates the tone arm and drops it gently onto the record, while other record players need to be placed onto the groove manually.
Automatic cueing systems are very desirable for beginners, since you won't have to fumble around with the delicate stylus. Anti-shock stabilization systems are excellent, especially if you want to take your record player anywhere for DJing events, or keep your record player in a heavy-traffic room.

There's nothing worse than a skipping record. Only consider turntables with replaceable parts. Some cheap turntables are impossible to get apart, meaning that if a stylus breaks you'll have to scrap the whole unit. Because record players will wear out over time and suffer in terms of sound quality, buying a unit that you'll be able to upgrade is a smart choice.
Most mid-range units should allow you to customize the belts, stylus, and the platter, if necessary. Part 2 of How much better, though, depends on your own preference for sound and your intentions with your turntable. Decide how much you can spend and set a price range accordingly. Plenty of record snobs with room-sized collections play their deep cuts on used turntables that sound great. Save your money for vinyl. Buy a good cartridge. Given the option, going big on a cartridge and spending less on a machine is always the better option. Since the stylus is the part that actual contacts the grooves, it has the most impact on the sound coming out of the speakers.
Always inspect used turntables. Vinyl collecting comes and goes as a hobby, meaning that the market for units, records, and other record-playing equipment can vary widely in price. It's always a good idea to keep an eye on used units to look for deals on high-end equipment that someone else has gotten rid of.
If you know how to inspect a record-player, this can be a great option for saving some money. Ask for a hooked-up demonstration of a record player before you buy it. You should be able to hear it. Bring your own record, so you can be sure of the quality. Check the rotation of the platter. Platters should spin perfectly flush with the base and shouldn't warble as they spin. You can adjust this, but if you're going to spend money on a new unit, you want to make sure you're paying for what you get. A record player with worn-out belts will warble and distort sound.
Inspect the quality and the pliability of the belts on a belt-driven record player to be sure the unit is solid. Belts should never be cracked and should return to their shape if stretched.
