It depends what you're looking for. There are numerous good scripts out there, but just because I like one doesn't mean that you will. If you can mention some of the things that you want the script to have (or not have), then someone can suggest ones that match what you want. Right now, I wouldn't know what was good for your needs... I use Invision (and a lot of my own scripts), but that doesn't mean it's the best one for you.
