I've been using Phatservers for my TGP posts and extra material for something like two years now, and they've been absolutely wonderful. Mike always gets right back to me on suppiort issues within an hour, usually, even when I email in themiddle of the night. And they are super helpful in offering to put stuff together and help a server-hopeless person like me figure stuff out.
Their prices are good, too.
I would highly recommend them.
