Hey everyone,
I'm one of the co-founders at ErgoDox EZ, this is an interesting discussion.
Without going into too much detail here (you can always email us if you have specific questions, we're happy to help), there are a few things I can help clear up.
First of all, no one has to pay at the pre-order stage, so we can't scam anyone. Pre-ordering an ErgoDox EZ now is only a means of securing the pre-order price when we go live on IndieGoGo. The price really is low, and will only be available for the first 48 hours of the campaign or so. No money will exchange hands before the campaign goes live.
Second, we don't plan on using 3D printing for mass production. You can read more about it on our page, but we've re-designed the case for injection molding (ABS). What you see on the website is our prototype, and yes, it's 3D printed.
As for legends on keys, big changes to the case etc., those could be stretch goals/future iterations if the campaign is successful.
