Are you thinking "regular" SCSI cards?

The TekRam DC-390 (Symbios Logic 53c* series, now LSI) are _regular_
SCSI cards.  The TekRam DC-3x5 (TekRam 1080 chip was it?) is also.

I don't know of _any_ SCSI _RAID_ card, which is typically a
microcontroller (uC) + DRAM design that has a list price less than a
3Ware's for the same capabilities.

Now you _can_ find used/older cards, like the Mylex eXtremeRAID 1100 or
2000 (206MHz StrongARM microcontroller, predecessor to XScale) with 3-4
Ultra80/160 channels for ~$100 these days on eBay (they originally sold
for $999-1,999).  But _nothing_ new.

Most of LSI Logic's new ATA and SCSI RAID cards based on XScale are
$399+.
