I have had an account with Nexcess.net for just shy of two months, and have nothing but praise for them in the way they have handled my pre-sales questions, signing me up, sorting out my VPS and providing replies to my support tickets within minutes. Resolutions times for my support tickets have normally been less than an hour. So far I have had no downtime, and the VPS I am on is very responsive. I would highly recommend Nexcess.net to anyone that wants a VPS or dedicated server for a reasonable price, and with top notch support.
