Build a Niche Store (BANS) is a software platform that allows users to easily setup eBay affilate stores in record time.
We managed to set our demo store up in about 1 hour, modification of the generic template took a little longer about 3 in total, but all in all it seems very easy. I would advise going with Hostgator as the instruction manual is geared towards setting an account up in this hosting solution.
So what do you get for your money? Well you get the software to use as many times as you want, you can litterally create hundreds of niche sites if you desire - although you would need a lot of domains.
