I have AWESOME service at Phatservers, have been with them for years. I have a managed dedicated box with 10mps uncapped + daily backups for 416/month. 2GB Ram, 11 ip addresses, unlimited email, domains, and user accounts. Not sure on the processor speed/HD's ect.
They have excellent tech support, and their Direct Admin panel is great for adding in users and domains since I do host alot of non-adult sites for a client.
Their tech support is the number one reason I'm with them because they have always responded very quickly to any problems, so if you are thinking of getting into hosting, make sure you have 24/7 response most adult webmasters are going to want that.
