I bought this kit as a test to myself to see if I could build it! I have the OO version which is beautiful but fiddly, so I worried about this N gauge one... I shouldn't have worried, yes it's extremely tiny but the way the lever frame folds together makes that part dead easy. The block bells and instruments are definitely for those with a lot of patience and nimble fingers though, because of the size you may find yourself swearing as they ping across the room (I'm still hunting down a flying block bell). Now I just have to make the box to fit them in
