6 years!!! Wow! O.K., now that's too long. I have to be honest, that's the single biggest consideration that weighs on me in my decision to make another custom. My others, which took around 2+ years (plus additional years for minor repairs, etc...) left me a basket case. I don't think I can handle that emotional roller-coaster again. I think that a 6+ year stretch would have pushed me over the edge!
Good luck my friend - and stay strong. This one definitely needs to be showcased once it's completed!
