I have the DW Foamies Yak Jr. and like it a lot. Very responsive and light, though I would guess not quite as durable as the electrifly yak. It can be flown with relatively inexpensive gear.

If you want another very durable option, how about the Mountain Models Panic 3D. Check out the crash video.
