Another thing to point out is that the lead-free and lead solders don't mix to well due to the different melting points.

The Novak stuff is pretty good.. but again, you need a good iron and it's really expensive!

I have been buying my 60/40 Rosin Core Lead/Tin solder from Radio Shack for the last 20 years... They did discontinue it for about 6 months way back about 15 years ago when all the lead free freaks were out and about... but the 40/60 less lead solder was crappy and difficult to use... glad them came to their senses quickly.

I imagine now that I'm using LiPo batteries these days, a 1lb roll is going to last me years!
