I've been toying with the idea of switching from OScommerce to Zencart. Last night I decided to give it a try. I'm happy to report that I will keep Zencart as it seems to do a great job without all the clutter.
Congratulations Dawnsday, I'm glad to hear you did a switch and it ended well for you. If you aren't happy with something on your site, you should always try to find a way to make it better.
