What server host do you use?

[Lamoc]

I currently run a group of ~10 people on a server running off of one of my machines. I'm looking at putting the map/world onto a dedicated machine. I'm looking at putting in anywhere between $7 to $20 a month into a good server. Does anyone know of any good server hosts? So far I've found a some server hosts with good reviews but I want to hear from you guys.

Top hosts I've found so far:

Any suggestions?
