OK... Wall Wart Bad Idea for someone who would have to ask what size!

Thanks for all the responses. Like I told one person. I am dumb as a
box of rocks when it comes to electrical stuff. Some of it I just
don't get. I get all the mechanical stuff just fine, and most of the
computer stuff, but not the electrical. I guess with that said, do
you think the best idea would be for me to buy one of those break out
boards from Doug Fortune or Bob Campbell? The Campbell board looks
really nice. I just hated to spend the extra money when I might could
make due with something else. I guess I should think that I have this
much invested in my setup, what's another $100.00
Thanks again for taking the time to answer.
