I've got two Rackshack servers. They're a decent price, they stay up, and I have plenty of bandwidth. What more is there?
Support? I wouldn't suggest someone without a Linux background venture into this world. If you do, be prepared and take your time making changes. The support people will try to help you but it really is a big boy's game. I've found many times more information available on RackShack's support forum.
