I inquired about their services a short time ago and they were very prompt with their answers and quite helpful. I ended up getting a dedicated box deal that was too good to pass up, but I wouldn't hesitate to try them after a good pre-sales conversation.
I actually downloaded the server stats script last night. That is as far as I have gotten so far with clookhost.com.
They seem okay and I have not seen any bad info about them through searches. Only thing is the guarantee is 14 day and not the traditional 30 day, but I think that if you are going to go bad it will not be on the 15th day but in plenty of time to deal with.
