Aw, man, I just can't really get up for this one right now. The community needs to convince me this one might have a shot at finishing up in less than 5 years.
Plus, I don't really think TMNT #3 is that memorable of an issue. It's mostly a big car chase scene and vehicles in motion are a big artistic challenge (for me at least).
I think I'd much rather do TMNT #4, 5, 6, or 7 with all the crazy battle scenes and strange looking characters like Utroms, Triceratons, etc.
