The other day I received Signature Plastic PBT spacebar samples. The good news is that they are all pretty thick.

They are from top to bottom: DCS, SA, DSA. I must say that quality is very good and they do not seem bent or deformed.
Bad news is that mounting points position is all screwed up. I doubt they would fit any keyboard as they are now. Stems are all few mm (or fraction of a mm) off from the standard position. I have to ask them how much would be to redo just the stems.

Anyway I believe this is a pretty good news nonetheless.
Awesome
