Oooooo.. my favourite. :)

Price/Performance != Correct always. I've had several Promise IDE
controllers (VL2400+, VL4300+), and they were GREAT. *VERY* fast
controllers, averaged around 8M/s steady. Gods, I miss them. ;( Anyways,
back on topic. :)

I seriously doubt it. We still don't support the Promise PCI UDMA/33
controller. And I HIGHLY doubt the truth of their claims. 25M/s? Maybe
with UDMA/33. *MAYBE*. But VERY doubtful. Drives aren't THAT good. IMO,
your absolute BEST route would be to go with either a DPT non-caching, or
a Mylex non-caching. I have a feeling the DAC960-5P (IIRC, that IS the
model#) is a bit out of your price range. ;)
Also, if you go with DPT, don't buy cache from them. It's just standard
ECC, which you can get cheaper if it doesn't say 'For DPT Caching
Controllers' on it. :)
