I have had a dedicated box with
www.webair.com for over 6 years and never had any problems at all. When I need something done I write text support or Mike or Gerard and it gets done. I like the service so much I ordered another dedicated server with Webair this morning for some of my sites. I also have a 100mbs server over at
www.choopa.com and they have been alright as well for the last couple years.
www.yellowfiber.com is another great company I have a server with and Zak will take care of you. Two thumbs up for all of the host mentioned above.
