yeah we, well at least i watched in early 90s sayin to myself wtf?!
i recently got an estimate for a tri (20b?), just sucked the price, id like any info anyone has on just building the main unit, i know theres a whole lot more to do with ancil sys, and mounting thats not the big issue just getting it together is, thanks in advance

 

I suggest you start by looking up the price for the 2-piece eccentric shaft. That should give you a flavor of how the costs will add up.
