Either the high end Denon or the Victor (JVC) motor units are perfect for doing a DIY turntable. Lots of information on either if you do a search.

DIY TT
I am looking at the Denon DP-3000, which appears like it might be able to slide out and mount into a homemade base?
Basically I am looking for a dual arm setup.
Also my existing TT only takes 1 arm, and it is limited in which arms lengths it can support.
Or are there other drive units which might be better suited to such a scheme?
