I voted DCC and here's why. Twenty-two years ago when my son was 10 we build a 4 X 8 layout "together". It was a lot fun and gave us something else to do together. 17 years ago when we moved we had to "dismantle" (wreck) the layout to get it out of the house. Last year my wife encouraged me to start MR again for stress relief. I started reading about DCC and that clinched it for me. So DCC is really what drew me back in to MR. It's been great fun ever since I received my Atlas Commander and a Hand-Command throttle ($190 plus shipping). Now I have 3 throttles and my friends (mostly the granddaughters) and I can run 3 trains (we can't handle more than that very well) without thinking about anything but the turnouts and what we want the trains to do. DCC wiring is a bit easier and less tedious and less expensive than DC. I use ground throws for walk-around operation and 8 switch machines for turnouts that are hard to reach or hidden. I have 3 small panels for turnout control and will have a couple more to turn off some sidings and service tracks (someday). I'm not bashing DC. It's just that DCC has opened up operation for me so that I can run trains the way I always wanted to run them. DCC is great fun. I highly recommend it to anyone, especially newcomers (like me, really). For less than $200 you can get a good "entry level" system and some decoders. That's not really much compared to the cost of a completed layout, even a modest one. My Atlas system is pretty basic (and simple to use) and I don't think that it will be "obsolete" any time soon (No more than my 10-yr-old TV or my 15-yr-old digital VOM or the 8-yr-old PC that my daughter uses for e-mail and word processing.) DCC is about running trains like trains are run and I love it.
