Bill:
Is there any belt PSRUs that you have seen that you would recomend? What
brand would you choose?
Also, what would you do to improve it, and why? I like the idea of a belt
drive, myself. They seem to have
been around for a long time with a pretty good track record from what I have
heard. Cheap to maintain also.

The big problem with a belt drive is they waste precious space inside the cowl by 
uselessly lowering the engine. This almost precludes using one rad under the engine.
It gives more room of course over the engine which is of little use in most
airplanes. In only a few designs like the Kis Cruiser and the Lancair
320/360 is room above the engine real tight and that only by an inch or 
two.
