mini-z's are great except for the fragility of ASC models. if you're into just buying & placing for show, then you're in heaven... if you want to actually USE the models on a track, forget keeping them pristine & damage free. maybe the cracks and broken fenders add to the character? dnano is the best... startup cost is a bit high, but compared to total startup + extended cost of mini-z, you're around the same budget with either choice. 2 of my mini-z ASC are already damaged and on the "memories" shelf lol
