Believe it or not, the prices you encountered at Radio Shack aren't all that
out of line. The days of hobby surplus stores, where you can just hop down
and buy a suitable transformer and components for $2 or so are long gone.
Components today can get a bit costly. I don't have a Radio Shack catalog
with me, but they used to make a nice little 12v 3A power supply, and it used
to sell for about $30 or $40. I see a nice little 12V 4A power supply in
Amateur Electronic Supply's current catalog. It's the "AIM small power
supply, model 38-384." It sells for $39.99. AES's number is 800-558-0411.
Unless you get ambitious and build it yourself, I doubt if you're going to
beat that price by very much.
