Vic, I remember Astrac! I remember thinking how awesome an idea it was but never came close to buying one, nor the Hornby for that matter. UP, DCC is easier to wire than DC, so that shouldn't keep you away. But by all means see if you can find someone in your area with it to check it out before deciding. If you go into the Digitrax users group at Yahoo, they have a list of people by city/state who are willing to help newbies.
