why not just build your own cold wallet? All it needs is a simple USB, practical and does not catch unnecessary attention @DarthCoin has a great guide for that.
All these tools seem really cool and overcomplicated things somehow, and maybe you might want to minimize dependence on any companies?
Thanks, I'll check the guides out.
Hopefully can find some options for it outside of Rasp Pi for hardware (not exactly security purpose built hardware, nor designed to be).
