We're not talking about the drones that [the world's militaries uses to commit murder], but the small ones that you can buy and fly for fun and to take pictures.

You [could in 2015] order a micro-drone that takes HD video for just US150 from this IndieGoGo campaign. This looks like a real boon for shooting video. The HD video now is 720P but the camera just clips on; the campaign states they will have higher-resolution cameras available sometime after they get the backlog of orders sent out. Base price includes your mini-drone, free shipping in Canada and US, camera module, remote controller, battery, etc.
Update:That crowdfunding campaign went OK, but their subsequent one, MicroDrone 4, has gotten mired in detail and may or may not see the light of day "someday".
