Thanks, Larry. What a difference in price between eBay and Just Trains! That ACME buzzer I mentioned was only $7.22. That is why I posted here, to see if anyone had any experience with it.
What about the Electronic Horn Kit (6-8190)? If it sounds the same as to original then, as they say in Brooklyn, fuhgeddaboudit. But if it sounds more like a real horn I would consider it. Not worried about keeping my 2343 stock.
