Well, so far I used mIRC unregistered.

But Mr. Khaled said he would see what he can do regarding an issue with wildcard matching I moaned about, mostly due to my specific application of matching a token string so alot wildcards separated by token separators.
He implemented the much faster method in 6.3, and its amazing how much the overall speed of my big script has increased, I never realized how much I got used to the slowness it caused.

So yes, two days ago I ordered it. That is just.. fair.
