I was under the impression that methanol had the lowest energy content of the alcohols, ethanol next, and isopropyl the highest (though it needs more O2 mixed in when burning, if it doesn't get it, lots of soot results)
Also, the denatured alcohol I can find in hardware stores is over $7 a quart, the SMP stuff would be $3 for the same. It does look like gallons can be found for reasonable prices at boating supply stores, though.
