Hi,
The first two you listed "may" be duplicates, I didn't look at the listings very close, but the one on the FreeState FX is a different version.
The first two listed were 5U conversions they did from Braids eurorack modules by just replacing the panel and adding 1/4" jacks. So it's basically a eurorack module behind a 5u panel. It does have Moog standard panel coloring though.
The newest one on their site is a full redesign, where they took the Braids schematics and made up totally new printed circuit boards to accommodate the 5U format better. It's a gorgeous module and I G.A.S. over it just because of it's looks! ;-) This one has a deviation from Moog standard panel coloring since it's solid black with no white/silver vertical lines on the outer edges.
