I picked up 2 pairs of heavy duty Peerless truck chains at a local Central Tractor last year for $19. 99 / pair. I don't know if they're still available for that price but it might be worth looking.
I've used them on fire trucks. I wasn't impressed. They were very expensive to start with, and were frequently in need of expensive repair / adjustment. Even when new they never worked well at low speed. Maybe someone else out there has had good luck with them but I haven't.
Did anyone chek out the ONSPOT automatic tire chains? I know a few fleets have changed over from using conventional tire chains or sand units to them.
