To make a long story short, I have some N scale engines that I have been trying to convert and I really wish Murphy would stop trying to help me so much. Sooo, I said to heck with it and went and bought a new Atlas engine with a decoder already in it. To say I was disappointed in the performance would be an understatement. It was dismal - took it back. Can anyone recommend some specific diesel engines that EITHER have decoders from the factory and they have had very good luck with OR an engine that I can buy and then change over with little to no hassle. If it makes a difference, my club is using a Digitrax DCC system. Thanks.
