Intralasik and eye centers

Does anybody know much about Intra lasik, and/or had it done? It sounds like a less risky procedure, since the flap is made with a laser and not a blade. however, not many doctors in my area (Phoenix, a pretty big city) offer it. Only one of the "eye centers" offers it. I wonder if this is because it's fairly new & not as predictable--or if it's just because it's too expensive.

Also, for those who have had lasik/intralasik done, have most of you done it with those "eye centers" with several doctors, or gone to a small, private practice?
