The current buccaneer XY stage plate looks like it’s laser or water jet cut, which means the “we’ve designed it around stamped steel” part is not yet proven out.
Same thing with the plastic and aluminum case being made out of extrusions — an alu extrusion that large is never going to be cheaper than even alu plate run through a bender, never mind plate steel bent into a cylinder.
I have a real hard time believing they will be able to do it at this price point. If they do meet their goals eventually, I’ll be happy to order a production machine, even if it goes to $1000 rather than $500, but for now I think they’re way underpriced. And that means that I don’t think it’s likely that the Kickstarter backers will get their machines. Not that it’s a scam — they seem very well intentioned — but I think the money will run out before everyone has their machine.
