'Best Breadboard/Prototype system'
Donald L Burdette
I strongly suggest the solderless breadboard for "playing around" to see
what works. It's incredibly easy to change a wire or six if you get it
wrong the first time.
I have been known to go straight to PCB, however. I do this if the chips
are too large or fine-pitch to put on a breadboard Many of my circuits
use 64 or 80 pin surface mount uP's and RAM's, etc that make it really
hard to breadboard. In this case I generally review my circuit several
times over a week or two and have one or two others look at it as well
before laying it out and getting a PCB cut.
Breadboards are great for small circuits, low frequency analog (up to
around 50 MHz depending on your noise margins), and especially for trying
out new ideas that aren't sure to work.

i mostly do that, too.

what I usually do when I'm in doubt about a part of a circuit (not many
coworkers around here for reviews :-) is just breadboarding that particular
part, or making a "trial" pcb with enough space around the doubtful parts
for changes, and including some of the options i suspect might be indicated
already in the pcb, whether i will actually use them or not.
