product looks legit. but at $299 for multi-site, that seems very steep. especially when you compare what you get at phpBay Pro for $79 (comparison of one premium paid plugin vs. another - not on comparable features). $99 for multi-site would seem like a better price. but no lying - that

this plugin is based off of dan's original to what he's offering now:
Sourcebench - the web developer’s workplace » Wordpress review plugin (SB_Review)
Dan, if you're looking for someone to do a comparisson between the free options and your paid version, I'd certainly take a look w/ a complimentary multi-site license.
