It's helpful for those tempted into spending their hard earned cash on cheap chinesium junk with no warranty or support.

If you buy two machines you will at least have spare parts...assuming you get lucky and the parts are interchangeable.

Can't you have a set of tracks made that are slightly smaller.
Odd as it may be, but there are companies plastering "custom made tracks" signs at every other intersection around here, like they were Domino's Pizza signs.
