I have a crop of low end machines, Promark Shadow (works and flies wonderfully) a Vivitar Sky View 360 ( interesting machine, dual GPS, RTH, follow me, circle me etc. has a rubberlike shell to it), Sharper Image DX-4 flies super, couple of Sky Riders including the hex (these are amazing flyers and the apps are pretty good. For flying FPV in the house I just picked up the Revolution Vizo, it's a small geared machine that is really stable and durable, I can go successfully from room to room with it, and the venerable air hogs DR-1, a little too fast for FPV for me right now but it's tough as nails and flies great. I will eventually probably get a DJI product, but I'm having a lot of fun with these.
