I have a trek for sale I got from a yard sale a while back. i was gonna ebay it and try to get $225 or so out of it. If you pay for shipping ill let you have it for $100 just to get you back on two wheels
Its a 54cm with a shorter stem dont have the measurement off hand but I believe it to be shorter than a 90mm.
No obligation just trying to help a fellow rider.
Im in Maryland probably be like $75 or less to ship
Specs can be found here
