I bought this for a camera from FT. Super small, super cheap.I got the batts from overseas for like 4 bucks:

When it was getting dark outside, with that little cheap camera, it was like daytime in the goggles. I was really amazed at how well it worked.
this for goggles from Amazon.

Believe it or not, they pretty well rock. They're amazing. Built in DVR and the picture is awesome. I added a Blacksheep directional antenna and another omnidirectional because the goggles are duel diversity.
I modded my quad above my skill level and it flew up over my head and behind me. Seemingly instantly. Given more skill, that would have been a pretty good mod. It was a rocket on steroids with a shot of nitrous.
I panicked, got the controls confused as it was WAY the heck up and behind me. Then I dropped it in a forest. There's lots of story after that as well. But I watched the whole thing in FPV the entire time. That quad and that camera are unfortunately still MIA.
It's a great combination of camera and viewer, and it won't cost you $800. The whole combination was maybe $200. It's still not cheap, but you are basically buying small HD TVs or a dumbed down tablet as a viewing platform.
Hope it helps. (Oh, Lord, I sounded like Hai-Lee with that last sentence. God help me.) I'll say: The Journey Continues!
