Where to get good deals on SCSI disk/tape drives

[mod at std.com (Michael O'Donnell)]

I wanna upgrade some old boxes and I'm looking for
recommendations for where to buy some SCSI gear.
I don't need anything fancy like wide or differential
SCSI, just lots of capacity for a reasonable price.
And it looks like I'm gonna need one or more tape
drives, too.

Just for fun I checked some places in the Nashua area
like Circuit City, Staples, CompUSA, BestBuy, etc but
found nothing.  I've only ever owned SCSI peripherals,
which I simply love, but SCSI is apparently unknown
to the mass merchandisers, who have plenty of truly
ENORMOUS drives for ridiculously low prices, but the
darned things are all IDE.  I realize I'll probably
end up going mail-order (or use the Web) but I thought
I'd ask about local merchants first.

Thanks.
