I've been using some Radio Shack 60/40 .32" rosin core solder that I got at the local RS a few years ago. It's one of those small tubes, and I need to get more, but that store closed. Is there a brand/content that is recommended for electronics work? That diameter seems to be good for what I use it for. Would something like this (link) be as good/better than what I've been using? Although one pound might last me 20 years!
