Agreed Ian. I don't do DCC and my 'guest operator' at home is my 4-year-old grandson. He can handle DC quite happily, as can his younger brother on their Thomas layout.
Whilst DCC may be taking things to a new level with sound etc, (I say taking as I don't regard it as having got there yet), it is no good if it makes the hobby unaffordable at the entry level.
