If you want large freaking quantities o' ethanol (denatured) or methanol, check with your local university chemical supply store. They normally sell it in 5 Gallon bottles for around $8-10. It has purity analyses on the side and all (it is made chemist pure). I would shy from methanol unless you are going SUPER cold ... ethanol still brings you well below zero and it isn't a nerve toxin. Just don't drink it, cos it is still about 2-10% methanol depending on the source to prevent students from drinking their final exam.
BTW, this is also a great way of getting ultra-pure water. Screw that "distilled" water from Wal*Marche, this is the real deal. Plus, if you ever want to do any glass/pyrex equipment, you can make damn near anything you want (and it is pretty damn cool looking, to boot ... turn your machine into a mad scientist's lab ... I knew a guy in college who crafted an octobong ... a huge glass sphere with legs that had a removable lid, one blowhole, and 8 seperate suck tubes with individual cutoff valves ... he said that when finished, he could pack it with a half an ounce at a time and could service a decent size house party with one go at it ... but that is a different type of mod altogether). A great source for people who want tall glass/pyrex tubes for resivoirs.
