You've probably spent too much on it already, and will spend a great deal more to get it just how you want. I suggest you mail it to me with all the parts, I'll pay shipping, so you can keep yourself from spending more.
To be truthful, the bike looks like it's worth it....if you are going to ride it or give it to someone to ride. I doubt many people are able to get as much profit out of bike that they would like when built this way if you are going to sell it. The real payoff is putting together a great bike and getting to ride it now and then.
