I've tried 60/40 tin/lead solder and noticed a huge difference between
the solder with lead and the stuff without, especially when I was using
a 15-watt iron from Radio Shack. That iron could barely melt the
lead-free stuff. Most of my solder joints looked like crumpled up tin
foil.

The main reason I was using lead-free solder was to make it safer for
people/pets, because I'm working at home. I'm not sure if that's a
good reason or not. I just wasn't crazy about having lots of little
pieces of lead laying around for unsuspecting critters to walk in and
track around the house, or the best way to clean the mess up, so I
avoided the problem entirely. :)

With that said, I may switch back now, as long as I can keep my work
area squeaky clean. What sort of steps to you take to keep everything
tidy? Just a decent broom? Or do you even worry about it?

Thanks again for the help.
