Conductive epoxy instead of Solder?

Has anyone used conductive expoxy instead of solder
to assemble a PCB? I currently apply Pb/Sn solder
paste, then pop the board into my trusty $29 toaster
oven for a couple minutes. But now I am trying to
mount some BGAs with lead-free solder balls. My
toaster oven doesn't get hot enough to melt the
lead-free solder. I could go back to Walmart and
buy a better toaster oven, but I would still have no
way to check the integrity of the solder joints. So
I am thinking of trying conductive epoxy. This would
be for prototyping, not production. If anyone has any
experience (good or bad) or can recommend a brand
of conductive epoxy that works well, please let me
know.
