I've worked and customized a ton, and I can tell you that FSR script is the BEST (but fairly expensive).
Sorry, I do not. I've been thinking of developing one, but have never really had the time to get around to it.
FSRevolution is the best. It does hog resources though and can be buggy and insecure. But from what I've seen of other scripts, it definitely has the best admin interface and features. But maybe I'm a bit out of the loop also. If money weren't much of an issue I'd say defintiely get one custom-coded.
