don't get me wrong the computerized programs are awsome.
But i personally would prefer a controll system i could hold in my own hands and have the feel of more control over like this controller set by Digitrax The Duplex Equipped Super Chief 8 Amp Extra Set this gives you all the options of the computer system plus being able to walk around your layout and stop trains while you are right by them potentially saveing time and annoying walks to your train that you have stopped and more train time.
This set also offers the capability to run multiple trains at once like say 8-10 and still have routes. This is the best set on the market and is around 650.00 dollars but they offer cheaper sets for people who run smaller layouts or use less trains like the super empire builder extra but you loose the ability's for routes and costs from 335.00 to 550.00 dollars, and from what i just read you will have to buy the amp packs throttles and so fourth anyways the computerized version at least what i could find on it ran through Digitrax amp packs and controllers so they are kindof just an exstension of the anolog systems alowing for the storage of more locomotive data and ither such things could be wrong though. could you post the link of where you found the one for 99 dollars?
