I just updated SingleHop's dedicated server listing since they are now offering 2 GB of RAM on all their dedicated servers.

Interestingly enough they also have that "Free upgrade to double the RAM on any server" offer... and I asked them, it still works!

So you can now get a P4 HT/3.0 Ghz with 4 GB of RAM, 250 HB HD, 5 IPs and 10 TB of transfer/mo for just $139/mo. Pretty nifty deal!
