For that kinda price you might as well just buy a welder. Even if you use it only a few times you got your moneys worth.
As a general rule I do all my own repair and maintenance work unless it requires specialized and very expensive equipment. Just do your research first and take your time. It's worked for me so far. I've probably saved thousands on just my car upkeep alone.
Besides, I don't like other people touching my THINGS when I'm not around to see they're not causing even more damage.
