Don't do this! Have a competent dealer set up your deck...and don't look back. There is a lot of good info in dvddesigner's post...including the video from Peter Swain ( an expert on LP12 set up_). But, if you look at his video and see his expertise, I think you can see why he is in such demand....and why it really isn't that easy a task to set up the table...correctly!
As to the power supply, go with the Lingo 4 unless funds allow for a Radikal D. IMHO, first upgrade your bearing to a Cirkus, if it is not already there...huge bank for the buck, IME.
