After more reading and trolling through the net more than I care to admit, I'm about to order the Headplay unit. For the price (or even a bit more) it seems to be the best HD solution available. I already have the HDMI installation on my controller. Apart from a cable, is there anything else I should order with the unit - or something else I should look at or wait for that I might have missed that will give me HD (720p) FPV for the P3P? I have to admit, the size and portability concerns me. And - best place to buy?
