Nice bike - 22" frame fits most riders.
I had the 17" in similar condition. Paid $50, sold for $90 after installing new tires. Local cash deals at both ends. It was a great rider, and the 17" camelback frame is great looking, but I needed to make room for a 20"
If the tires are good, and I needed a bike to ride, I'd pay up to $100 for that, knowing I could recoup some by selling off the speedo and gen/light set. The seat on there is also worlds more comfortable than the standard Speedster saddle.
