Ha. I actually just cut mine about a week ago for the first time ever. I go with a low buzz-cut, so it's not hard to do. Not really a ton of skill, just set it to the length you want and go back and forth like a lawnmower. I do make the sides slightly shorter, then blend it into the top, but it's not too bad. The mess was the worst part...had to sweep the room and shower afterwards.
But it looks pretty much exactly like a regular cut. No one's noticed. And I have the money, but just tried it on a whim with my new hair grooming kit (which was originally just for my facial hair). Fun times.
