This may not be applicable to many folks here, but we're seeing a lot of obscenely priced Mac Pros on a number of different craigslists. Perhaps the worst was $1950 for a MP 1,1 8 core. Most listings don't even identify which version it is, the giveaway usually being the OS or the RAM speed. So: If you're considering a MP, don't get ripped off. A MP 1,1 should be closer to free than not, and a 3,1 not much more. Hope this helps someone here from being taken advantage of - there are lots of unscrupulous sellers out there. And don't get me started on all the people "selling" pirated software . . .
