Should I continued to use my 1 pounds (2.2 kg) of Kester lead tin 60%/40% solder? The silver based lead free solder are becoming more available. I still have a pound of lead solder that I inherited and the solder dates back to the 1950s. These are for my electronics hobby stuff like op amps and 555.
