I can tell you that certain workstations get bought up by government. Any of the personal Alphas or the slimline models are rare. The one that used to be dirt cheap and easy to get was the DEC Multia, but that's turned into gold, too. I remember buying one for $50 off Ebay at a certain point. The one to really lust for is a DS25, but you do have to do a special boot process to get Tru64 running on it (not that hard, though). I'd recommend against trying any rackmount system unless you have an isolated rack. They are extremely loud and heavy. The only one worth having IMHO is the ES80. Any of the GS series that use the QBB architecture are very failure prone and buggy, even though the fastest Alpha ever, the GS1280 is in that family sporting the sexy EV7 CPU(s). The easiest ones to get are DS10's and DS20's. Check Islandco, who often has them in stock and tell David that Swift sent you.
