Depends where I am searching, you want to use the equivalent of keyboard (ie tastatur, tastiera, claviera, клавиатура, 键盘, etc.) ... I also often search for other brands Cherry has made boards for or use Cherry keycap like Amiga, Commodore, Apricot, Peacock, NCR, Alcatel, WEY, Olivetti, TA, Nixdorf, etc... Wow I just gave a lot of 'secrets'... though anyone could find this out anyway if they wanted to research as I have.
I have seen Olivetti G81s on ebay.it many times, but never able to get seller to ship outside Italy (not even to other EU country, wtf is wrong with them anyway?) and know no Italians to proxy. Pretty much the only reason I don't have one.
