Well... TextWrangler is the best one out there, IMO... if you don't like that, well I don't see which you would like... 😛 😉
SubEthaEdit 2.2 is still free, if you can get it... but the new version, 2.3, is no longer free (like you said).
What do you want to use the text editor for...? That might help people suggesting appropiate editors for your use... 🙂
