#1 Pegasos. Sold out. You can't buy them at the moment
You are correct that you can't buy them at the moment but not because it is sold out, just because they are not delivered to the dealers yet.
Sold out to the dealers, not to the end users. :-D
and doesn't have AGP and is sans a PCI slot
What are you smoking ? Both Pegasos1 and Pegasos2 have AGP/PCI.
