I paid just $300.00 for my mint-condition '91 Schwinn PDG 5. That got me a lugged, brazed, double-butted chro-moly frame made with Tange OS tubes and circa 1991 Shimano 105 kit.....
I'd have paid double what I did to get my butt on that bike, if that's what I had to do to make it mine. It punches the right "retro-grouch" buttons for me.
A bike built on a tig welded hi-ten steel frame with a sloping top tube?
Eh..... Not so much....
