The gold '78 Raleigh was a $20 CL find. The green one, a '73 Raleigh, my bro-in-law found in a pile of bikes destined for the scrap metal man. Both turned out to be 531 frames Super Course, and are great riding bikes. I went nuts $$ on the green Raleigh build (my first), the gold one was a totally "how cheap can I build it?" budget build from mostly parts bin. Frames are out there, happy hunting. There is a sweet 3Rensho in the BF classifieds now, too small for me.
$20 on local LA CL.
Low buck build.
Free from the scrap pile. Cracked brazing, stuck seat post, incorrect fork, but nice Capella lugs and decent chrome underneath ugly paint.
Finished bike, spent too much, but worth every $$$ ... to me.
