Never heard anything good about lead-free solder. Haven't tried it, and not looking forward to it. Personally, I think the lead poisoning thing is blown way out of proportion. I've been soldering for about 30 years, and molding miniature figurines (lead-tin alloy, well mostly lead...) for almost 20 years, no major health issues and mostly sane. You have to ingest (eat) lead to get poisoned. Just wash your hands before handling food.
Anyway, there are a few tutorials on lead-free soldering around the web, think it was instructiables.com where I last saw one. Been meaning to read through one sometime to see just how much of a hassle it really is, and how to deal with it.
