I buy Everclear by the half gallon in Montana. I forget what it costs, but it's not expensive. I use it with shellac flakes to make musical instrument varnish. Of course when I tell the seller that, they laugh and say "Sure, that's what everybody says". But really. I do not drink (over 25 years).

I think that it's a good idea for backpacking stoves because you will end up inhaling toxins from methanol if you use denatured alcohol. Such toxins have been implicated in some types of degenerative mental conditions, including Alzheimer's. Read End of Alzheimers by Dr Bredesen. You might start to be more careful with the toxins that surround us. It is one of the "insults of modern life".
