I find myself in a similar situation to MakeshiftMuse, in that the information in this topic has been immensely helpful to me, and I wanted to thank you all for assembling it.
But since this is an OEM quality discussion, I have a question about Leopold. I can see that Leopold is listed twice (under Topre and Unknown), but the only comments for them are that they are 'Good', where they are sourced and what type of keyboard they sell.
Is there anymore information about their boards besides the general comment of: 'Good'?
