Try http://www.rcsystems.com/  (RC Systems, INc.).  They list the Tyan
Yorktown I & II
cards at $95 and $125, respectively.  The Yorktown I uses the Symbios
(NCR)825 (fast/wide),
while the Yorktown II (according to RCSI) sports the 875 chip
(fast/wide/ultra).

Interestingly, it is very difficult to find Symbios-based boards on the
web (or anywhere else).  Tyan lists the Yorktown I on their website,
claiming that it uses an 825 chip,
while Symbios replaced the 825 with the 825A on their site almost a yer
ago).  Tyan does
not list the Yorktown II--RCSI is the only place I've seen it listed.  

Symbios responded to some mail I sent them a whil back with information
suggesting that
Insight had agreed to retail their cards, but I've never seen them
listed on the Insight
website.

Here's the mail from Symbios:

If you're going to buy one of these, I'd strongly advise getting at
least an 825 or (preferably) 825A card (fast-wide; 16 bit path) even if
you don't yet have a wide disk
device, to offer yourself an upgrade path.  This advice is based upon my
belief that
'disk speed' is extraordinarily important to performance of a *nix-base
system.  Fast
cpus are a waste if your disks are slow (IMHO).  At $95 (compared to
maybe $65 for
and 810 or 815), these things are CHEAP compared to Adaptec, Buslogic,
etc. cards for PCI
SCSI.
