The sponsor with the $399 price for the Base 3 is Nassau Hobby Center, but they will require a 10% non-refundable deposit. Charles Ro and others are at $340 or 350 or so with no deposit. Personally I'd just wait and see about early reports . And, as I suggested, consider buying an inexpensive Universal Remote that will control up to 3 LionChief, LionChief+ or Legacy locos equipped with Bluetooth (last few years). Just check the outside of the loco box and it will be noted whether it can be controlled by the Universal Remote. Out of stock some places but available from Lionel and Amazon it appears.
