Best thing to do would be to go and talk to either a local club or go to some of the local shows and see if they have any DCC layouts running there.
Unfortunately, we are too far away (Worthing) but at least two or three times each year we have people come to a club night to ask about DCC. We let them play with one of or DCC layouts and it helps to settle their minds about cab control, the "two-wires" issue and how to get going in the first place.
Again, when we take Loftus Road to exhibitions, we get people asking how we use DCC and we are quite happy to let peole have a go at driving trains, we show the underside of the baseboards so that they can see how it is wired and happily stand and talk about the pros and cons of various systems.
I think that until you have had a chance to play with some DCC kit and see what it is truly like, don't go making big decisions just yet...
