I have three MTH AIUs . I decided not to use them. I put a slight crack on one case but it works fine. I have one box that I can find. $85 each and $75 for the one that has the crack in the case.
I also have 5 Lionel SC1 controllers for sale. They are like new except one has one station that is not working. I had these on my layout for a short while and they all work fine with that one exception. I like these and I think they were great. $75 for all five.
Shipping extra, PayPal as a gift is fine. If interested ,jba435@gmail.com
