In days past I would just suck it up and use vim or similar, which is fine for smaller projects or quick scripting. This time I will be undertaking a larger project and I'd really like the convenience of a feature-rich IDE.

I'd reconsider vim. Not to start a timeless argument, lol, but I use (g)vim and eclipse for development in a bunch of languages including perl. IMO, the editing features in eclipse are between non-existent and pathetic -- it's just cut n' paste; you might as well be working in notepad. I think people who have not had much experience with software like vim don't recognize this. Note that most of the useful eclipse/IDE features -- autocompletion, subrountine indexing -- are available as plugins for vim and, at least WRT to perl, work better.

Sigh. I sound like a rabid fan. But honestly, don't right vim off for this; it is hard to learn, but very much worthwhile in the end.
