Don, I think we have been through this at least once before. 

I'm pretty sure the Camoplast belts you had came from the old Camoplast plant, wherever it was.  

The belts everyone else is talking about come from the former Caterpillar plant in Emporia KS, which Camoplast bought sometime in the last few years. 

Belts are made for all the tractors at Emporia now.  I don't really think there is a big difference in quality depending on what you order them to fit.   There are several different tread designs and belt constructions availible based on your intended use and how much you want to pay/how long you want them to last.   When I was talking to them earlier this year, I was told that the old Camoplast belts which had been built in wherever were effectively discontinued and future production would come from Emporia.
