I really don't recommend acid core. That's for plumbing, I think. The problem is that if you don't wash the joint and neutralize the acid, the joint will get eaten away over time.
I've been using some Kester brand 63/37 rosin core, .020" diameter, and it's very nice. I don't think you can get it at Radio Shack, but most mail-order places carry Kester.
Otherwise, the .020 60/40 rosin core from Radio Shack is good enough. Pretty standard stuff, can't say anything bad about it.
