This company, recently mentioned by George,have various crimps and chain ends, so you might browse here:
http://www.alchemyandice.com/.
Another source would be Rio Grande: http://www.riogrande.com/ Dennis.
Alchemy & Ice don't do the ones i need sadly and Rio Grande are reasonable....but after you pay customs charges, it doesn't work out so cheap.
Thanks for the links, but i'll keep looking.
