Has anyone tried this yet? I keep going to the site almost adding it to the cart, but I usually won't buy a thing without reading some reviews. The price is right, and it would be a good way to see if higher voltage is something I would like, but the key attraction would be, does the new Ego Mega DCC fire up without fiddling with the connection pin? I've got 20 of these cartos here and they are really awsome on my ego 900 but would like to try it at different volts. Not wild about having to be plugged in, but for 25 bucks it's something to consider.
