I also agree, special Thanks to Bruce!

I have had very good results with a Walmart electric skillet and a IR thermometer from Harbor freight. I preheat the boards to around 180 F. Then turn it up to full heat, once the solder paste has flowed you turn it off and let cool. Its like magic when it melts!
The idea is descibed in a Sparkfun tutorial

Dave's advice on less solder paste is really good, which I have learned the hard way.
