That is a great looking machine. The parts and components that make up the kit look like high quality items. Are the smaller, black idler wheels made from plastic? No bearings or bushings in them, so I would guess they have to be some sort of harder plastic. Same as the tracks? Also, hard to tell, but does the larger aluminum idler/tensioner wheel for the tracks have a ball bearing or bushing in it? Just curious about dirt getting into all the workings of the tracks. Haven't heard of any complaints. Seems like a robust machine. You are making me want one more and more!
