Lets talk about the resellers
With so many hosting companies out there, it is really hard to say what host is the best one because everyone offers things slightly differently. Additionally, being a hosting community here, most of us have some relation with a hosting company one way or another, and our responses may pretty well be biased. It will probably be easier if you list some companies that you are interested and let us do a break down comparision for you instead of throwing up such an open ended topic.
