2walla, jossurf, 343sp, Rosster6028, lenhard2007, and everyone that posted before - thank you very much for all the input. I am leaning toward using one of Miller R-C Products large drive cones and insert, and find a lightweight automotive (gear reduced) starter to build my own. This is definitely not final because I'm in no rush and if I find a premade starter for the right price, I'll go down that road. At least if I build it myself, I'm confident that I'll be able to get the correct inserts from Miller as or if I need them and I doubt the parts for the auto starter or the starter itself will go away either - piece of mind is a good thing.

Thanks again,
Todd
