A couple of things to note:
1. I love my Callaway irons. I've got the Tungsten-Titanium and swear by them. I'm a pretty awful golfer (just started a few years ago), and I tested lots of irons before I bought those.
2. Try and find one of last year's models. Just like cars, the golf club companies come out with "new and improved" clubs every year (usually around Christmastime, I think). You can't go wrong picking up "last year's" set and you can generally save a bundle doing it.
