I have a reseller account with Gigapros. Their service is incredible. I haven't had many reseller accounts but I just can't see how any hosting company can be any better. I get responses and solutions quicker than I expect. Their servers are really fast. They never seem bothered that I'm asking questions and their price? Honestly. If you're a reseller, would you rather pay less for less service? As it is, they're price is one of the lowest. When you consider the level of service you get, then the price is a bargain.
When you need a hosting company to be more then just hard drive space I recommend Gigapros.
