Inserting a model here:

Enterprise 1200 (MegaRAID 428)
If $340 is super cheap.. then this is ULTRA SUPER TURBO CHEAP II at $109 for
the 2 channel version
(yes with battery backup too!)
33Mhz i960, 2 or 3 channels and up to 128MB of cache (FPM Parity 72pin
<=70ns albiet.. hard to find)

Seems to be working very nicely, no problems (I avoided the hanging issue
with ami controllers a while back)
and definitely speedy w/ 3 discs in raid-0. (i really need some more cache
though, 4mb doesn't cut it according to mike smith :)
