I would like to use through hole components so anyone could assemble them, but surface mount components do have EMI advantages. I've soldered a lot of surface-mount components in my toaster oven.

P.S. - e-mail coming
On most of the breadboards I've tested in a noisy environment I have put massive numbers of .1 and .01 caps on all chip power leads as close as I can to the chips - and place them on all power lead, regulators etc... Helps so much to quench those transient spikes...
