Asking what's the best turntable in any given price range is much like asking what's the best car in a given price range. A lot boils down to what your priorities are and personal taste, as well if you want to consider used as well as new. Used will usually get you more for your money when it comes to turntables.
I'm a lifetime idler drive fan, myself, loving the pace and timing they have. Others prefer what belt drives do best, while others like direct drives. Matching a tonearm to any of them requires careful thought as to what type of cartridge you plan on using. High or medium compliance moving magnet? Low compliance moving coil? Lots of things to consider. I'd suggest reading up on the subject on various analog forums (this one included) and asking more directed questions about specific models when you think of them.
Here's a few other forums with lots of experienced turntable guys.
These are just a few that comes to mind. There are many more. You should be able to make an informed opinion after picking a few brains from some of these guys. Between the guys here on Audio Round Table and the guys at the other forums listed, there is a lot of turntable knowledge available.
