I very much agree with you on that. That's why I've recently have been trying out Cryptosteel's seed signer. It is worth a look:

Just think of it like a physical engraving seed signer. Just do what Obelix does with his menhirs in a way (:

you are very welcome. what irritates me with all or almost all hardware manufacturers is they do not allow you to read the source code. what they do is a comparison check in lenghts of bits of the downloaded code which is not the same as reading and understanding a source code.

they tell you that you need to RELY on the community that the code is clean and if there is an attack or a bug, someone with advanced kills will warn everyone . this is the exact opposite of the seedsigner which is: 

everyone can download the source code from the seedsigner website and read it.
do not trust, verify !
