I would buy one in good condition all decals in good to fair condition. For fun I bought one that was built the year I was born. Also it is nice to have a Centennial machine, they run just a little more than the others, but usually not more than an additional $100. I also like the white/green ones. That will be my next purchase. If you go with the 222, they are quite rare and run substantially more, they have a free arm.
Maintenance on a featherweight is easy. Happy hunting.
