I've been looking around for mechanical keyboards that suit my needs. So far, most of the high-end keyboards seem identical to me, including Das, Filco, Leopold, etc. What I haven't seen however is a similar keyboard with extra shortcut buttons such as volume and calculator. It isn't critical for me to get these, but for the price range, I'd prefer not to make any compromises.
Despite living in the EU, I want a US layout as I rarely type in my native language. This makes it hard for me to avoid wasting money on shipment. Das is available to me without much hassle, but at a whopping 130 euro price tag.
Recommendations are appreciated.
