I have a reseller account with HawkHost. I haven't had it for more than 3 months, but I am very impressed with Tony and his service.
I offer hosting to a few of my marketing clients who need small sites - nothing major. But I've had occasion to ask a few questions. Tony's answers are always very prompt, and very professional, even when I ask questions most other folks would be tempted to answer with, "Well, dummy. . ."
I have a reseller account on another service, but I am seriously considering moving away from that one. Not only are HawkHost's prices much lower, I get better up-time and faster, better responses to tickets.
Not an all-inclusive, rake-them-over-the-coals review, sorry. But for my needs, HawkHost has been great.
