Hey guys, I currently have a 2GB server with slicehost which ends up io bound a lot of the time (big db). I'm thinking about getting a server with more ram - 4, 8, or 16GB depending on cost. Do you know of any good providers out there who are low cost - or who provide higher ram packages with lower bandwidth and hard disk offerings?

I'm looking for cheap as I'm completely bootstrapping and doubt I'll be bringing in any revenue in the next few months. Any suggestions appreciated.
