Their inhouse support is simply the best. There is always someone onduty to answer and resolve your trouble tickets 24/7. I was going to move my single shared hosting account away from them a year or two ago, and they convinced me to move in my reseller account that I had elsewhere with them and stay.
With the new manager that came in, they now have resellers, VPS, and dedicated servers. Not the cheapest, but certainly one of the better webhosts out there.
