Picked up a couple 11 oz. bottles of this stuff at the local Dollar Tree:

The label said it contained methanol and other proprietary ingredients, but it was clear and burned cleanly in my stoves without leaving any residue, just like HEET.
I've also experimented with an mostly ethanol additive called EthaMax ($1.50 for 12 oz) which did put out a lot more heat than methanol, as would be expected, and stunk a lot more, also expected. It also did leave a small amount of gummy residue in the stove, but was able to wipe it off.
Here in warm southern California, gas stations don't carry HEET, only auto supply stores and Walmart. The SMB stuff is cheaper, and you may try other brands if you can't any other source of alcohol for your stove.
Of course, if you can find a racing gas supplier in your area, you can get methanol by the 5 gal can for a lot less per ounce.
