They are very good bikes if you aren't worried about weight or keeping up with much faster bikes. Zukahn1 is right though, building that one up is a project for someone that really wants to have one, but there are complete ones for a couple hundred. It looks like that one was originally Sunset Orange, a good color if it was in good condition. They are good solid riders but a little stodgy compared to many others, You know, one piece crank and all... The 60's versions were all in sparkly colors whereas the 71'-73's also came in the solid "Mod" colors.
Heres what I mean by Panache'... My old 68'.
I got it for $150 and its all original. It just needed a good cleaning and service. If you look you will find, they are out there
