Kinda. There was a peak, but it was pretty close to my original "interest
gauge". The place I need to be careful is making sure I remember to order
more than a couple for myself. ;-) Since it's a lot cheaper to order more
up front than do another run later on, I generally take my "final call"
number and order 120% of that. That way I have a couple for any
stragglers, and a couple spares to leave unpopulated as reference boards
later on.

Also-- as the board complexity goes up you might need a couple extras for
manufacturing defects. AP Circuits has been pretty good about getting me
good fabs, but without electrical testing on the boards you're never really
sure until you try it. (Which is why I like to pre-assemble the more
complicated stuff like the Sega Multigame. The multigame averages over 28
holes per inch for components and vias...)

Another question for Anders-- is your design 1-layer? (that should help a
lot on price...)
