You do know that stamping your seed onto washers and putting them around a bolt is one of the most recommended ways to keep it in metal, right? How is that overpriced?

And I may understand more than you think. I've been storing coins since 2012. I've tried out 6 HW wallets and a seedsigner. I even tried a brain wallet once but nearly lost that due to having only a human brain with human-level memory recall.
