I’ve been using Inmotion Hosting for just over a year now, and I can say they are definitely the best company I’ve used so far.  Thier prices are low, they have great tools available within the admin control panel, and their support is top-notch! My only complaint is they don’t offer reseller accounts.  Here is a quick list of features offered in thier business level accounts:
