I want to know,is the CrystalSky monitor compatible to the Phantom 3 Standard ? If yes,where i can get this monitor ? ...and how expensive is it?

Until DJI release it, all anyone knows is all on this site:  http://www.dji.com/crystalsky

DJI Aerial System Compatibility

The CrystalSky monitor can quickly connect to the Inspire series, Phantom 4 series, Phantom 3 series, Matrice series, and Osmo series (except the Osmo Mobile) over Wi-Fi or via a remote controller USB port, depending on your specific product.

The monitor should be good for any drone using the DJI Go app

I ´d read both 5,5" and 7.8" has the WIFI and they have an installed DJI Go inboard. I´d opened this topic before i ´d a look into the site. I must look for a DJI trader near by me. Does anybody knows how many bucks i need to buy it yet?

Like I said ... no-one knows anything more than what you'll read at http://www.dji.com/crystalsky
Beyond that all you'll get will be guesses
