GREAT job Brother!! I know you're proud. Wear it proudly and in good health.,,,itsa Beauty!!!!
As for cost.... I'd venture to say within 1.2k of a nice preowned gen is likely a good guess.
But with a build like this I'm certain it wasn't an issue of cost....it's all about the self accomplishment and pride.
Millions can say they own a gen 16610 but how many can honestly say "hey, I built this one myself" ??
