Go pro. I think it's just better in every way, especially if you can find a place you're really comfortable at. And even if you don't do it that way forever, you get to see what they do and have a better idea of how to do it yourself.
I had it done professionally the first couple of times before I started doing it at home. It does hurt, but its much cheaper going to a pro can be a bit expensive if you do it every month. However it is all worth it, ingrown hairs are not a problem if you exfoliate :)
