I have no idea what "not expensive" means to you, but for all its worth, the free releases from Mobius are better (especially for small servers with 20-30 people), with more working features, than all the L2-Scripts you can find leaked on the internet. I've been working with a client, who has paid for L2-Scripts sources and they are, for the lack of better word, disgusting. It appears as if they were taking updates from the leaked versions and were not even bothering to remove the comments. By the looks of it - simple copy-paste. So, it would appear that even the paid Scripts versions are not much better, if at all, than the leaked sources.
