Radio Shack's universal power converter works just fine.  Yes, there's
some hum, but at a low enough level that it's not annoying.  It has
several voltage outputs, including 3V, and six different plugs, one
of which is bound to fit your walkthing.  The plugs can have either
polarity, so that's not a problem.  The only connector it doesn't 
come with that I'd like is a 9V battery type.

It's definitly worth the twelve bucks.
