Look at the esky lama v3 or v4, both are $100 (get two for the price of one EZ or CX/CX2). FYI though that these are not really stable outside, any wind at all can cause serious problems. Blades strikes between the top and bottom blades as well as between the stabilizer bar and the top blades are common when flying outdoors. Almost all heli's smaller than 450 are going to have trouble dealing with wind.
