I wonder if I should submit a second entry to the Clunker Challenge. I rode my $70 Panasonic Sport Deluxe 21 miles today (to Great Falls and back, on the Maryland side). It rode like a champ. The only upgrades are a $2 light, a $10 bike computer mount, and a few cents of oil on the chain. So I guess $82 total?
