Santanaali,
I assume you're going through belts quickly because the metallic backing is wearing thin. Read the thread Thom linked to for a notable improvement in both belt life and sonic performance.
Note: the ever thoughtful Mosin suggested kapton as another potential belt material which might (or might not) provide a further improvement. Haven't had time to try that yet.
Rickmak,
A Galibier, Redpoint or Teres capstan might be adaptable to your Raven motor. Might have to drill out the hole for the motor shaft. Otherwise they're perfect for a 1/2" tape, assuming the capstan diameter is compatible with the speed range of your motor controller.
Sonofjim,
Agree with you and Stiltskin that the experiment is worth hearing for yourself. The majority of Verus testers on Teres BD tables have found it to be an upgrade. You might too.
OTOH, if we had a two table budget we might sell both and buy one of Mosin's Saskia tables. Haven't heard it in our system to confirm all aspects of its performance, but it's certainly the most speed-stable table through transients we've heard. It outplayed every table at RMAF in that respect, regardless of drive system.
So many tables...
