I'll give some feed back to that. I was planing on ordering ten.
Not that I'm that bad at soldering, but some people at work could use
some practice.

Note that ten packs aren't cut up; you'll need a scroll saw or other
pcb cutter with a narrow kerf. I use a #2 blade. I'm going to cut up
the singles first, and if I have any blades left (they dull quickly on
fr4) I'll start working on the ten packs.

A Hong Kong/Chinese board fabber, YukShing Circuits, sent me some
FR-1 that could be good for a
"product" version of "The soldering challenge -- Are YOU up to it?" advertised in circuit cellar. His company has edges left over from cutting some panels out and they give 2Kg of these away as a way to drum up business... With FR-1 you would have a built in heat indicator if soldering too long and hot -- the paper-phenolic board will scorch. Cutting them is easy -- score and snap. The dust is much less dangerous than the glass dust that FR-4 makes when sawing it hobby-style, (see silicosis). With soldering irons as the main way to assemble, the extra heat of no-lead solder would not be all over the board, just at the hot iron tip, so not likely to even scorch if melted quickly.
