That's what I thought too. The brainmaster design is quite
simple. The Biosemi design is just 3 op-amps, 6 resistors,
and 2 capacitors per channel.

I mentioned that PCBexpress accepts Eagle files and does
low-volume orders. Also, I keep buying this permanent
(soldered) breadboard material at Fry's Electronics. It's
a large sheet with plenty of space. It's said out like a
normal breadboard (actually several on one sheet) , but
it's thin stuff metal, and you solder the parts on the
back. It can also be cut to size with tin snips. I think
it's called "network designer's prototype board" or
something like that. I've built quite a few circuits on
this stuff that are permament, they work well and are
very robust.
