Do yourself a favour and just test drive the Macgregor M455's,
I brought these irons after testing the Ping G2's, Callaway X18's and the Mizuno MX 23's. There is no doubt in my mind that these were by far the easiest to hit, and they also look a lot nicer than any of the forementioned clubs. Another big bonus is they're forged and you could probably get them considerably cheaper than any of the clubs you are looking at.
Todays golfer (UK publication) has (and still does) rate them as the best game improvement irons out there for the past couple of years. The proof is in the pudding and I have slashed my handicap from a 24 to 13 in 12 months using these irons.
I think the only problem you have is that Macgregor are not deemed as a fasionable club maker over in the States. Fortunately living across the pond I don't seem to suffer from the same sort of club manafacturer snobbery as you do.
Here's a brief review from Todays Golfer
