I like the idea of the RetroTINK-2X, but seeing that the device handles composite and S-Video then the lack of any means of adjusting colour (and tint for you NTSC folks) kind of dulls the appeal of it to me... that and the creator's attitude towards some things.
As in, during a YT interview he was asked why the RT-2X didn't have RGB input. His answers were along the lines of "The chip I chose doesn't support RGB" (Fair enough) and "It would have been trivial to add a RGB>Component transcoder in effort and cost... but America didn't get RGB, so I couldn't be bothered."
In fact, looking back at the creator's YT vids on the RT-2X, the smoothing filter was originally going to be permanently on ("I kinda like it.").
Also, the RT-2X's 4:2:2 colour downsampling may also put some people off. It's not a big issue with the Comp/S-vid inputs but is apparently noticeable on component with some images.
I'm holding my breath until somebody tests the thing with a PAL C64
Until then, the Extron DVS 204 I recently got is serving as a useable stopgap. We need to get some reverse engineering type people on it, the main components are two FPGAs that have dedicated config eeproms...
