Lots of choices in the 70's - 80's , both European and Japanese.
Don't count a bike out just because it doesn't have a cromo frame . A high ten frame is heavier true, but sturdier. less likely to get dented. and at 6'5" and 270 lbs. a guy like me wants something that can deal with a bit of weight.
Most of the lower end Raleigh bikes used 20 / 40 hi ten which is a step above the gas pipe frames others used. I rode a 1980 Record ace for a couple years that I converted to upright bars and a 14-34 tooth 5 speed freewheel and is was a great townie.
Here is a pic of a Nishiki I just customized. Started out as a 36 lb. tank with steel wheels and cranks and now after going on an aluminum diet weighs 28.5 lbs.
