Its impossible to have the best hosting, whilst also being cheap, like others have said pick one and go with it. See how their service is and if you don't like it, find another.
Find a niche market and use that to gain reputation etc.
These "niche markets" have all gone. Period. They are more than occupied.
Some of these people that want "cheap" and "best" will no longer exist in a matter of a few weeks until they realise this is no longer a get quick rich business.
I love these types of questions as there is no correct answer, leaving the thread open to discussion. Since you can't really use the best and the cheapest when discussing a single reseller provider, perhaps you could rephrase your query, like possibly who would you recommend as the best reseller provider in the $10 range? $20 range?What host is the best and cheapest in delivering reselling?
