I have done several boards using solder paste and a cheap, non
convection toaster oven. My most recent was a LQFP176. I have not
lost a chip yet to excessive heat or popcorning. I sometimes have to
wick solder bridges, but that is easy.
You still should have a good soldering iron, but using smd's and a
toaster oven makes things much easier in my opinion.
