These threads on here about quality lately seriously kept me from buying any new motive power this holiday season.
I ended up buying a Lionel Polar Express tender shell on the web, it fits perfectly on my postwar tender (screw holes are exactly the same) which is pulled by a restored nearly 70 year old 671 turbine that runs flawlessly and is easy to fix. I also bought some used Polar Express cars for cheap. It looks awesome and nobody knows the difference. I don't need any headaches running modern junk.
