With the mere existence of the Komodo, I think the "Red Tax" may not exist as much anymore.
That said, that is the point of BM, Panasonic and Z-Cam, I suppose... very good/great cameras for less. But it doesn't take too long of a search on YouTube/Vimeo to see why someone may pay a little more for the Komodo instead of those other cameras.
Of course, I can only speak for myself. Everybody has their own needs, wants or opinions.
For me, I am done with any camera over a certain price that doesn't offer some form of internal raw or ProRes. I'd much rather shoot 1080p raw or ProRes than 4K on some crappressed codec.
With regards to this post, I don't think this mod is really geared towards your average video shooter, so that in and of itself, puts it closer to Komodo territory. Even with the mod, at its heart it's a Pocket 6K and although I have seen amazing work shot with the camera, I'm unsure if the upgrades are worth the cost of admission with the other options on the market.
Assuming my price assumption is correct, a C70 with its DGO sensor or an R3 or Z9 may be better options.
