Astrx,
I can tell you what someone that will be looking was thinking

background - Super clyde getting back in shape after years of 60 hour weeks behind a desk. I bought a steel hybrid and have been riding everyday. I was thinking when a 20 mile ride is a regular workout, I will want more of a road bike to get more miles in.
My thoughts were
1) how much would the frame be
2) steel would be good for me as a light bike wont help me for year(s)
3) if he would ride his own bike and the price was good I'd sign a release
4) what sizes are universal for loading up the frame
