I've used the FoxTech goggles for about a year now with no problems. Requires a power input of course but has an integrated receiver. At that time it was roughly a little under $400. I felt it was a good choice but my only issue was a lack of clarity. Example; I couldn't see if there were any deer between rows of the orchard I fly over. I now use the Carl Zeiss Cinemizer and am very pleased. Excellent product. I bit expensive but after weeks of wondering if it was going to be worth the investment and better than the FoxTech, I have to say it was.
