What should I buy, the trezor https://amzn.to/2NdhnKE or save some money and get this keypay wallet https://amzn.to/2ulIMmQ ?
I have been dabbling with Ledger Nano S. It handles many currencies. For a long time it's only direct connection was with Electrum on Tails Linux (very good) or Chromium plugin on Chrome (less good). They recently released a standalone Linux client for it (very good).
One feature I like, is that you can add a second password, for a second amount. Plausible deniability.
