"Klotten" woudn´t be much far from here (i assume 150/200 kilometers), but that thing isn´t that worth. Sound yes; overall weight, size and power consumption-no. I prefer my SoundMaker, it has this typical ARP Stringsound (possible that it uses a "real ARP StingSection", as many devices did from this era) and it is in my opinion really not far away from the sound of a U310.
