Laser Hair Removal for the Back/Shoulders/Neck

I am contemplating laser hair removal for my back, shoulders and neck. My hair color is dark and I am very hairy. I also tan easily, but have been out of the sun for 2-3 months now. I did one treatment about 3 years with little to know hair loss coming from that treatment. Is laser hair removal the best bet for permanent hair removal? Are there different types/methods for laser hair removal? Is one better than the other? How many treatments will it take (range)? Are treatments bi-weekly, monthly, bi-monthly? Is it going to cost me a fortune? Any help or suggestions would be greatly appreciated. Thanks,
