got mine off E-bay from a distibuter in canada. they also have a 1.20 4 stroke that retails for $199. Ive heard they are made in the same factory as magnum but I havent seen magnum come out with a 1.20-4 yet so i dont know. If you hold the ASP 91 up to the O.S. 91 they look almost IDENTICAL. but i swear my ASP has more power. but for the money savings I would buy another. There Is a US distributer here http://www.excelhobby.com/excel_hobby_053.htm

they are out of stock right now
