A couple of us on here have done it and I think they all turned out pretty good. But personally I don't think I'll never do it again. I'll spend the $400-$500 to have someone else do it. If you're tight on money then do it yourself...someone on here has instructions how to do it, I bought my instructions off of eBay.
Someone recently had a nice write-up, and I think he mentioned that he used Chris's (Don John's) article on his website (I have not seen said article, so I could be totally wrong).
