Does anyone know if it's possible to give yourself a Brazilian wax?

I usually go to a day spa but it's costing me $50 plus tip/month--pretty pricy for a poor college student. I would stop, but it's sorta become an addiction now.

It would be cheaper and easier if I shaved, but I've heard too many horror stories about the razor.

My hair is pretty fine from all the waxing so I'm thinking it shouldn't be too hard (or painful!). I'm mostly just wondering how to do the back part.
