Welcome, @
DBDad!
Deals are still out there if you look hard enough. Was at a bike swap last week and there were deals aplenty.
Last year I scored this '88 Schwinn for $150.
I have since upgraded it to a 3x9 setup. 80s Columbus Tenax-tubed Schwinns are great riders.
If you are into Raleighs, don't overlook the Raleigh Racing USA models from the 80s. Very nice-looking bikes, and they tend to have a good reputation as solid riders.
Models would include the Prestige, Competition, and Super Course, among others.
