CityMax is the coolest tool on the web. I needed a website to sell my stuff and it took me forever to find a provider that would allow me to build, host and maintain my site so easily and for less than $20.
Its awesome because unlike the other site builders out there, it is integrated with eBay, Paypal, Google, Yahoo, Shopping.com and just has everything I need. I am their biggest fan.
(CityMax claims that more than 172,000 sites have been built using their software.)
