Tell me please, what kind of wallet is better to use to buy tokens?

I usually use myetherwallet, but if you want to protect yourself as much as possible, it's best to buy an offline wallet.

What kind of offline wallets? Can you link to them and how do they work?

At the moment, there are two leaders in this market. Ledger Wallet & TREZOR Wallet.

Thank you so much. Are there cheaper wallets? I understand that these firms are proven good work. But I want the choice to be more than two wallets.

As far as I know there are still such wallets as COOL WALLET and KEEP KEY.
