I had a pretty bad experience with their support.I used it on Berman Hosting.. Never had a problem with the VPS itself, though support it kinda slow to respond..
We run scrapebox, and gscraper over on amazon EC2 servers, Depending on what your budget is, amazon servers are pretty good, and no waiting on someone else for anything. Resize, or downsize at the click of a button. I think were paying $3.25 a day for windows 2008 4 gig ram machine with a dedicated IP. Amazon is a bit higher, but the flexibility is what I really like.
