I also have a Y3, which I think its one of the best examples of Lionel American Flyer. I belong to the ACSG, and I have run my Y3 at train shows for well over 500 hours.
I just did a quick search on eBay and there are 244 items that show up on a quick search of "American Flyer Santa Fe". Here is another Locomotive you might like:
