Yes, TJ, we all want one. Bring your checkbook, because none of them is cheap.
This is just the latest in a series of beautiful, miniature engines, hand built by geniuses laboring somewhere in obscurity. Actually, my favorite is the whole miniature Ferrari race car (including functional engine, gearbox, suspension, etc.) built by some crazy person with WAY too much time on his hands. Listening to that tiny flat-12 Ferrari revving is at LEAST as good as the sound of that miniature V8.
Good luck in your quest. Let us know if you get one.
