You can download an evaluation version of Komodo here.

I've tried an earlier version of it for a couple of days, but I wasn't impressed with the speed (but I'm working on a Pentium Pro 200 with 64MB :-). I'm an Emacs fan myself, and although the CPerl-mode is very handy, it doens't do too much handholding. Code completion and other nifty gadgets are handy, but I think that thinking about what you're doing is going to make you a better programmer than relying on IDE gadgets. But maybe that's just me.

I'd suggest that you download the trial version, use it, and if you like it, buy it.
