Good choice, these goggles are praised on youtube being the best cheap goggles. I've considered buying this only for the dvr option. That diversity is also very nice.
Can go cheaper though, but then it comes without diversity and dvr. (My goggles don't have diversity btw)

I really hope there will come cheaper versions of the Fatshark model. It's not much more difficult to build then the Eachine goggles, only not done yet. Would be great to get some chinese Faksharks for like €100.
