DCC is evil, it turned me into a newt ...
... now, as an amphibious salamader I have experienced several problems with DCC. Firstly, your wiring needs to be 100% otherwise shorts will turn a good operating session into a damp squid. Secondly, the cheapo chips arn't that good and therefore it can be quite expensive when you do decide to digitise. Thirdly, you'll get sucked into the wonderful world of sound and end up spending sooo much money you'll get love letters from a bloke called Darling. And finally, the ergonmics of most throttles arn't set up for lizards ...
Do you really need it ... naaaaaa ... you can obviously build a fantastic layout without it!!!
Keep up the good work Peter, think of all the lovely new trains you could buy instead of the DCC chips and throttle B)
