I buy the Kester 63/37 .031" dia solder off of the Bay. I never buy a pound of it because it has a 2 to 3 year shelf life. I go to the Bay and a guy on there will sell 30 feet (1.1 oz) of the 24-6337-0027 solder for $8. This lasts me 2 to 3 years and then I buy it again. If I got a pound, it would take me 20 years to use it all.
