i've just done this, went with the 007 and the pro dvr card recorder to wire in, $57 total. vrd2s seemed like the featureset was less fiddly than the 800 but don't remember why, or it had some minor function the 800 didn't.
anyway - when i was checking out, i noticed eachine have two new goggle models on banggood!
the vr006 is a bit cheaper than the vr007, afaict the difference is it uses a tiny tiny 3" screen, so it is even lighter. get it?? "006" is smaller
the vr011 i can't remember, except it was another build with diversity and no recorder. looked pretty bloody heavy. iirc one of the advertised features was for people who wear glasses.
