Yeah, I edited and hacked up the code in my older version of ktools that I don't even want to think about upgrading.
Symbiostock looks nice, and runs on wordpress, but it still looks no frills compared to what you get with ktools. I'm sure it doesn't run as fast, either. Who knows/cares. Selling direct is not something I would ever do over again. Too much time/pain in the rear to deal with for such a small return, unless you happen to be some sort of special SEO wizard or have bottomless pockets for google adsense to drive traffic.
