While this does seem to be a good DIY project, and one can build it over time, thus spreading the cost out over a period of time, I am a "I want it right now" kind of guy, and will just pay the freight for a kit.
I do think Todd is right, once all the nickle and dime things start adding up, the price will climb, but all in all, I think it is great for the guy who wants to fab some of his own parts and such.
For now I'll keep my Wilwood's, but if there is a better solution, I may be persuaded into trying something different....
Good work, to both of you guy's.
