That's great to hear!
I had had been looking at the U23b's on the website for a couple of years and noted no product availability. When I realized that it would be unlikely to just be able to go to my hobby shop and pick one up I reluctantly decided to call and actually 'place an order' for one Earlier this year. Glad to here that I may get it before the end of the year!
I do have an O54 turnout that has given me problems for a while now and since I purchased it about 15 years ago, I figured I would just buy a new one as I keep having engines stall on my current one. I never imagined that if I were to go to my hobby shop that I would find these out of stock. Maybe I'll see if they have one when I get my new engine.
