Replying to Quadcopters, what do you guys use?

Hey guys, I recently purchased a starter quadcopter (hubsan x4 h107) and I love it. I've been flying it around and have pretty much mastered this thing to its capabilities. I'm in to filming/fpv quadcopters, because I like to film aerial shots, and think they bring a whole new perspective to a movie/edit.

I'm looking into buying my next level quadcopter. I'm in the 500$ range, and specifically looking for real time FPV flying, stable video, and decent range. My idea option is the Hubsan x4 h109 pro, but it doesn't seem to be coming out any time soon. Another thought of mine was a DJI phantom, but they don't offer real time FPV for under 500$. Do you guys know of any other great quadcopters I could look into that might suit my needs?

Thanks
