I'd probably opt for the pre-zimmed Elefant that Hinsky is working on, but that being said, I have the Ferdinand premium in the stash. It comes with plastic parts in case you don't want to make PE fenders and the such. It's price tag is pretty low, they can be purchased on ebay for around $30 with postage, but they aren't common there.
For the magic tracks, I've recently made one long run and use the Testors glue that comes in the pink bottle with the brush and liberally slather the run, wait an hour, then form around the drive sprocket and idler. I'll stuff some cotton or something else between the hull and the wheels to give a sag. Wait at least 24 hours and they should be rock solid. I leave one link undone, so I can take them off to paint.
