WooHoo!!! That's how I feel about my new Digitrax (well actually it was the one my LHS was using on thier layout) I got it and an MRC Sound decoder and I love it. Still tinkering with the speed settings and such as I would like to set it for slower accelleration and deceleration but I lve this setup. My CSX SD-35 has nnever run so smoothly before. And the best thing is I got sound in it for only approximately $60 USD. instead of 130 or so for the soundtrax decider I was looking at.
