I went to my ob/gyn office for it. I did a compete Brazilian, underarms, and the "peach fuzz" on my tummy. It was supposed to be 6 treatments but it ended up being 13 over 2 years. I got the last 7 treatments for free because even on the highest setting I still had hair and I complained. They were very nice about it. I finished last year when the technician sat me down and said "you're very fair skinned with very thin hair and this is as far as we can go." The best removal I got was my underarms. For some reason the hair is darker there. I didn't even attempt my legs because the hair on my legs is so light and sparse. Even if it grows in you can't see it and I only shave my legs about once a month.
I'm very happy with the results. Is all the hair completely gone? No. Did it go from a forest to a small shrub? Yes! I used to have to shave my underarms every day and now I do it once a week and there are so few hairs I don't even need shaving gel, just two sweeps with the razor and done. For me that is a HUGE improvement and well worth it.
I found it hurt less than waxing. For me, waxing hurt for hours after and was still red the next day. Plus, I hated having to let the hair grow out to be waxed (especially my underarms - gross!). They had me at the highest setting and the pain lasted for the second she had the laser on the spot. Twice it was red/sore for a couple of hours after, but not as bad as waxing.
I agree with a PP, if you can get a Living Social or Groupon deal, and it's affordable enough that you won't be kicking yourself if it does't work, go for it, and see if it works for you. You might have great results.
