Thanks for the info and the explanation... I'll look into this.
One question though - how do you determine how much current this thing can handle?
Off topic, about those pesky "wall-warts," I found this product from CyberGuys to be the solution:
Liberator. It's essentially a 1ft extension chord. At first I thought it was a cheap gimmick, but I bought one anyways. I then proceeded to buy about 5 more. These things do wonders for ya!
