Good turntable under $500 ?

I agree with the Pro-Ject Debut Carbon recommendation, but you would do better buying from another vendor. Crutchfield, AudioAdvisor and MusicDirect are much better choices with great customer service, without the snooty and arrogant attitude displayed by Needle Doctor's personnel.
