I know it isn’t apples to apples , but for a baseline, I bought a 1978 Raleigh Pro that needs a paint job. Last year I saw an ad for it on CL for $150 and it was frame, fork with Campagnolo headset, and BB. I inspected the frame and it was in good shape except of course for the paint. I bought it and am still in the build process . I will ride it for a while and if I like it , will have it repainted.
