We have 6 dedicated servers with them. Well, actually we HAVE 4, and the first 4 were all setup within 24 hrs of payment (one of them was setup on Laborday weekend!) ... we ORDERED 2 more on Friday and are being told that they won't be ready until monday. So, in other words, sounds like they are a little bit backed up right now.
Other than that, support has been ok, not the fastest ever but reasonable, and the price is right
Webair is A.O.K. in my book.
On another note, all of my virtual hosting is through RealityCheckNetwork.com and I have nothing bad to say about them at all. Their support is EXCELLENT and their prices are damn good as well. Been with them for a long time with no problems.
