I looked into digitrax. I was actually going to use them for G-Scale (going to use them on my HO Scale sets) until I saw AristoCraft demonstrate the TE Revolution system at East Coast Spring 2009. I'm not here to compare products, especially since I'll be using both for 2 different scales. I just found for the Outdoor layout I'm building, and even the indoor layout of which I run 2 locomotives at once, I felt AC's Multiple unit system worked best for my analog units. That and the Revolution reciever will be powered by about 120 amps of power supplies. I'm wired into our garage circuit. Even with ComEd installing a 200Amp power line, and redoing the interior electrical (yeah we did this a few months ago), the garage circuit is all by itself. No one uses the circuit there anymore since I run the outdoor cords to the house's outside outlet, so I figure that I'd tap right into the garage circuit. The outlet down in the basement is wired right to the garage. The outdoor plan is to keep that outlet. Since it's going to be track powered wireless, I can keep everything inside the house and not worry about anything. Staging tracks will be leading outside so I can keep the track connectors and electrical wiring inside the house. Again Digitraxx is a nice system as well. I've worked with it before and I'm happy with it for smaller scales.
