If it matters - I have had luck over the last two months in getting
two DWL-520 cards, one Rev A1 and one Rev B1, from  Believe they can get more of these
if you push.

See above on the 520.  The way I ensured my purchase would yield the
correct device, as I have with other devices of particular hardware
I wanted, was to get with the tech support folks at the vendor and
get them to put hands on the one I would be sent, and check it out.
Never have gotten any resistance when I ask for that (other than
the occasional "does it really matter to you?").

Note also that the Netgear MA 311, a PCI Prism card, is readily available
at a number of places, including Circuit City and BestBuy.

I agree that finding the cards in the configuration you want can be
something of a challenge, but I'd say they're far from scarce.  With
the number of variants shown on the Absolute Value Systems page,
there a quite a few to try finding before throwing in the towel.
