What day job? I doubt if 'privately repairing old HP calculators' counts :-)

I'd rather keep buffers that talk to the outside world in
pin-through-hole DIPs, since they're likely to get zapped at some point,
and it's a lot easier to replace a (socketed?) DIP than a SOIC. Anyway,
board area (and component count) are not too important for 1-off
prototype designs IMHO.
