I use the cheap coloured KMC 1/8" chains.. According to my logs, the first one I used lasted me 4,553.20miles (7,327.67km) - those was mostly summer (though a fair amount of rain). The one after that which went through a pretty wet/icy/snowy winter lasted 1,812miles (2,916.45km).

I don't mind the quick go-through rate, they cost me $8USD and do the job just fine.
