knowledge base and their support is very responsive. Granted I had a simple question, but I got a response in less than 5 minutes when I contacted them the other day.
With that being said, they might not be the biggest VPS provider, but they were cheap and were recommended to me by a member here.
With my current VPS plan, I've got a 512MB VPS with 20GB of HDD space, and 1TB of bandwidth for 54.99 a year.
The ironic part about that is that is around the price I was paying for my shared hosting originally.
