I too have had an Fast Track Ultra (non 8R model) interface for about 7-8 months, and so far it's been great. The preamps are the Octane series which are the same preamps as the higher end Profire interfaces, and they are quite good sounding. I always hear people complaining about M-Audio's drivers, however, I've had no problems what-so-ever with the drivers for the Fast Track Ultra. I definitely recommend it, it's probably one of the best interfaces in the $350 price range IMO.
