I’m releasing the 3rd theme for bloggingtips next monday so it was good timing that you posted this. My first two themes were bought and released about a year ago. I too bought them through sitepoint. The 2nd theme was ok but the first theme was very badly coded and I probably should have cut my losses and not released it.

I’ve used a designer for this theme release and I’ll probably use him again for future projects however if I see a bargain on sitepoint I’ll probably snap it up though I’ll make sure I view the source to examine the code first.
