I had laser done in the U.S. and loved it. I paid $4k for full leg, bikini, and underarm - you can do it much cheaper here for sure.
To answer a previous question, every time you get treatment you have a permanent hair reduction of 10-20%. The reason you have to space your appointments is because the laser can only target and kill actively growing hair folicles, and at any one time only 10-20% are active.
I wrote to my laser guy in the U.S. to ask him for information about getting lasered here on behalf of another friend, and this was his response:
~~
Two devices for your friend to stay away from: IPL (also known as Intense Pulsed Light) [It does not work.] and Diode Laser (they say that it doesn't hurt but that's because it just stunts growth, it doesn't eliminate it).
The key questions that one is supposed to pose when choosing a laser clinic are the following:
-Does the laser clinic have the right kind of laser for my skin type: Alexandrite for Fitzpatrick skin types 1 to 4, and Nd:YAG for skin types 5 and 6 (and types 1 through 4 who have been tanned or in tanning)
-Does the laser clinic ask you for a medical history
-Does the laser clinic do test spots
-Is the technician certified (Google "CLHRP" to see what certified looks like) or just a nurse who is trying to make a quick buck running a laser
-Does the client/patient feel comfortable with the clinic, the staff, and confident that his/her safety will be of primary concern and satisfaction of secondary concern

I hope this helps. I wouldn't worry too much about getting burned or scarred as long as the place seems legit; using the laser is not that complicated, just a point and shoot procedure.
One thing you definitely need to be aware of, however, is that your legs need to be shaved immediately beforehand or it's not as effective. So, ask if they want you to shave before or if they will shave you there. If they say it isn't important and there's no need to shave, DO NOT use that place!
