Best racks I've ever worked with for turntables are Rix Rax:

However if they are out of your price range, or not your style, the second best solution is a wall mounted shelf. I prefer the Quadraspire (www.quadraspire.co.uk) to the Target because it provides more precise leveling using threaded spikes, and it also costs less and comes in a variety of wood finishes. But the Target is also an excellent choice.
