I'm not entirely sure what you're trying to convince me of. I did pay the $600, I even said that it's probably a cheap price to pay to treat the apnea.

That doesn't really change the fact that it feels kind of viscerally wrong to pay $600 to pay for two glorified pieces of plastic, and a part of me still does feel I could clone it competently. I haven't bothered for the aforementioned safe resin, and also because I already have it and I have enough money to just eat the cost and complain about it.
