Don't waste money on the V1 if you can get the v2 are a lot better if you can find them.Here ya go, a cheap head mounted set for under $50 USD.

The Dominators are good, I'd suggest getting the Fatshark Domv2.I'm after a little more portability, and simplified.
I've seen some predator v2 for less than £100, or I can get dominators for £150 with RX.
How are these prices?
I'll keep my black pearl monitor untill I know I'm happy with goggles then sell that to help pay for goggles I think.
