Rob,
From what I have been reading the lead free solder is more brittle than
solder with lead and more likely to suffer failures. One report I read
said that adding zinc to tin/silver/copper alloy solder made the break
jagged instead of clean and enabled the join to continue to function.
It just doesn't sound as reliable to me.

Hasselblad with no camera to sell.
The solder is actually mainly Sn now, alloyed with a few percent Ag, it flows
at a higher temp but it's not that different from the Pb/Sn solder process. I
know as I have witnessed a friends production line switch over.
