What is the best used ARC Pre-Amp to get?

With all the choices in ARC Pre-Amps I need to know which have these capabilities,are rated the Best and what the Blue Book is for them used?If you know of a different Brand that has the same capabilities then pass it along.

Phono Stage
Single Ended
Processor Loop-(If possible)
Remote Control-(If Possible)
-----------------------------
Looking at what to get in an ARC Pre-Amp.I would like to becapable of having my Lexicon CP-3+ SS Processor outside the Loop when using the system for Stereo only playback!Need a Phono Stage also.How would you go about it?

The newer ARC Pre's have a Processor Loop along with Remote's.Would like to either get an all tubes Pre-Amp or Hybrid with a remote capability.

Line-Levels are out because I do not want to go through getting a outboard Phono stage.

This newer model looks like it has the features I need ,but I would like to get a used model.
