Along comes JoomGallery. There is room for improvement, nice-to-have-stuff. But it works, it looks smart, it integrates nicely with my CSS. I'm just happy and eager for it to come out of beta.
Support: I had a few itches, they got answered. I got one real problem, they answered immediately and solved the problem.
By the way, I only have little experience with Joomla and none with SQL what so ever, but .XCloner just works like a charm.
