The action buttons are rather low profile. That's a red flag for me, because they could be of lower quality than regular (i.e. heavy-duty) arcade action buttons found on more generic arcade controllers. But they may also be just as heavy-duty, so it's an unanswered question for now.
I don't know, how can you tell that they're not Sanwa or Seimitsu? They look like they could be either to me... or neither. I feel like it's impossible to tell what they are just by these pics, but I don't see anything that suggests they *aren't* real Japanese buttons. Which could be one reason why this thing is expensive, if it's using actual Japanese arcade parts.
Then again, I'd have been fine with some cheaper parts if it got the cost down, and that design is just lazy. "Let's just make it the logo!" Their logo is fine as a logo, but it makes for an ugly arcade stick.
edit: just looked at the site again - first paragraph says they're Sanwa OBSF buttons.
