Each trezor is over $90 right now (the latest one) and it depends on where do you live. In a 3rd country, each trezor could be sold at more than x3 of the oficial price.
Both are secured and the only significant difference is its design and price, so in the end it depends in your personal preference.
And in my opinion, the ledger nano is muuuch more better than the trezor wallet, only because of the design and the hardware.
Maybe the trezor is very handsome, but you must know that it is more flexible than the trezor and it can easily be broken, and it is not happening with the ledger.
Obviously that if you take care of both, there is nothing of what you should be worried about.
But i am talking about LONG TERM.. that is why the ledger is the best one for me (and it is less than $69)
