I recently purchased a dedicated server and created some VPS's on it for my own use, just running GSA and CSX. I'd be willing to lease out 2 of the VPS's to other GSA users at a very reasonable price.
VPS's have 2 dedicated CPU cores, 2GB dedicated Ram, 50GB HDD, 100MBit port running WinXP.
Thinking I'll charge just $30/month per VPS which is cheaper than any comparable VPS I've seen. Let me know if you're interested.
