Oh man...I hear ya! I’ve been playing with PhpEclipse as well and...well...I just don’t get it. The debugger is the part I’m being most critical of with any IDE I’m looking at. So far the Eclipse debugger doesn’t impress me much...too much of a hassle really. The same applies to some of the others I’ve looked at: PHP Designer 2005, NuSphere PhpED, PhpEclipse. All of them just seem to fall short of my expectations.
I can see now why so many rave about Zend...their IDE is pretty damn good. Granted, it doesn’t have every stinkin’ feature that other’s have....but then again, Zend’s focus was on creating a solid IDE rather than one with everything and the kitchen sink. I’m pretty impressed with it’s debugging features...probably the best of all IDE’s, really. And, yeah, it’s a bit pricey...but the Standard Version is only $99, which is good for someone who doesn’t need alot of advanced features that the Pro and Enterprise versions have. Hell, I don’t mind forking out $300 for the Pro version if it means having an IDE that I know will work for my needs. And when you think about it, as important as your software tools are to do your job, spending $300 isn’t all that bad considering what you get. The average developer could make that back with but a portion of one job.

Since I still do alot with Dreamweaver, I’ll likely be hopping back and forth between it and my main PHP IDE...which right now looks like it could be Zend Studio.
