Hello Ric,
You may want to check out this site...Closeoutsusa.com . They carry old inventory of AMF products. The bad thing is they only have 16lbs or 12lbs stuff. I believe the price is quite low and they are all first quality. They are located in NY and I went there personally to pick up a black Jordan plastic bowling ball (for spares) I won on ebay. I got it dirt cheap and I did see all the AMF stuff they had there. I ended up buying the Ti-Hawk for $25.
Also for all you AMF fans out there.
