Which leaves me with BitBox01 as it's open-source and reputable.
I would not buy that old outdated version of BitBox wallet and I think this is a bad idea.It is inferior in every way compared to most hardware wallets that exist today and I don't think it's supported by Shiftcrypto anymore.
However, Shiftcrypto, which is the Swedish company
Shiftcrypto is Swiss based company, that is country called Switzerland, not Sweden 
Perhaps I should forget about the hardware wallet as I'm left with no choice. Your thoughts.
If you really want to buy hardware with cash you can visit some country that is bordering with Greece, like Bulgaria for example and buy BitBox02 there for cash.You can find Bitbox02 in many other shops in Europe, Croatia, Slovenia, Germany, Romania, Netherlands, etc.

I don't know if you want to use hardware wallet just for Bitcoin or for other shitcoins, but if it's only for good old BTC than you can buy Raspberry Pi zero locally and make your own SeedSigner signing device.
