I had it done in March of 1999. At the time, there were a handful of places in the States doing the procedure, but the guy I went to in Canada had been doing them for years, and had something like 12,000 procedures under his belt. I felt that the experience he had, along with reputation and references, made me feel more comfortable.
Cost was $4,400 US. Not sure of the cost now. My insurance did not pay for it, but at the time I did talk with some people and their insurance did cover it. It would have definitately been cheaper to have had it done in the States, but I wasn't concerned with price. You only have one pair of eyes! In fact, a lot of US docs were advertising 2-for-1 deals (both eyes for the price of 1). That'll make me buy a pizza, but not go under the knife and laser!
Here we are 3 years later, and I'd consider a US doctor. Again, it really depends on their experience and success rate. The doc I went to had records of all his procedures, along with percent breakdown of issues, problems, etc. Here's his web site if interested:

My vision was about -8.0, if that means anything to you. About 20/200. I couldn't see squat. The worse your eyes are, the less likely you'll get right to 20/20. I think I got down to 20/15. It's not an exact science. The final shape of your eye, and therefore the vision, depends on how the eye heals. Since the healing process may take weeks, months, or longer, it really varies by individual. It's basically up to the doctor how much to shave off with the laser, based on his experience, your age, your vision, etc. I think I was somewhat lucky in the fact that both eyes turned out with equal strength, and a followup by a different ophthalmologist confirmed that under a microscope there was virtually no scar tissue from the incision. He was very impressed with the results.
I had worn contacts or glasses for over 25 years (since about 4th grade). I finally decided to do it after yet another frustrating incident with contacts. I was skiing out west, racing one of those Nastar courses. Half way through the gates, I blinked funny, and one contact popped out and landed on the inside of my goggles. Flying downhill with one blind/unbalanced eye, I made it to the bottom and went to try and put the contact back in. Well by that time it was all dried out, and unsalvagable. All my extra contacts were 2 hours away back at the condo. So I had to ski the rest of the day like that. I decided that I'd had enough!
Good luck with what ever you do...
