I got mine ~1 yr ago at Duke (just before I finished residency). I always said that I would never let anyone cut on my eyes or my back. However, with the advent of the Visx 4 laser, and the CustomVue process, I felt that technology had reached the threshold with which I would be satisfied.
Mine was $1900/eye (normal is $2600/eye, but there's a $700/eye discount for employees). Mine was done by Alan Carlson, who is in the top 6 of all LASIK people in the US - I think he's done 12K procedures. However, now, what he did was just make the flap - otherwise, it's all automated. The written stuff says that the CustomVue is 25X more accurate than the manual, and that is why I don't have halos or decreased night vision. There was a cornea fellow in the room, but he didn't touch me.
One thing is for sure - you get what you pay for. For $500/eye, don't be surprised if you do indeed have halos or other problems.
