I'm so married to RGB output it would take some getting used to switching over to component. Composite, in the difficult-to-see demo, seemed way too fuzzy for me to ever want to do that. But (again, hard to see) component sounded like it was a viable option.
I like the overall look of them and the options they provide. But... not sure I'd be in the market. But I like the concept of a brand new monitor working with our old machines that looks period correct. If you don't have an Amiga with HDMI (most people don't) this seems a good option for some.
I think I'd want a closer look at the video output. And I know this is me just being picky, but I'm not a big fan of "DIY"-looking ports, especially when on the front of the thing. If I'm getting one of these for aesthetics reasons, I wouldn't want it to look cheaply made. I realize these are demos. I'd likely wait and see.
I didn't go for the checkmate case, either.
That being said, if I was a MISTer guy (maybe some day) I think this would fit that bill really well + a small checkmate case. Could be a legit way to go.
