A little late to the party but here's my entry - 1973 Schwinn Super Sport.
Bought for $30 at local estate auction.
Stripped it down, cleaned, polished and repacked bearings.
New Kenda tires, tubes and rimstrips $29 including shipping from Bikesmiths.
Yellow tape was $10 from Amazon, I would have preferred the original Hunt Wilde type but that was $40 (!) on ebay.
Shorty Wald fenders, two used inner cables, toe clips and straps all from my parts bin, figure $15 value. Total cost $84.
Just finished reassembly, still needs some fine tuning but plan to start putting on the miles tommorow.
