Well first, what is your price range? Second, are you buying a turntable for sampling, or do you want to be able to scratch as well? In general, you always want a turntable with a direct drive rather than a belt drive. Belt drive's break and slow down after a while, as well as taking longer to return to normal speed.
If you just want a turntable to sample with, and thats it. I would get the cheapest new Stanton you can find, I believe it's like 99$ or close to. Because 1, it is super cheap, and 2, it is really easy to sample your records with. I have a Stanton T.92 USB and it cost me about 400 with the warranty and what not. I'm really happy with it, but it isn't pro grade gear. I can do baby scratches, but without dropping close to a grand on your turntable you just aren't going to be able to scratch like Q-bert.
