I've yet to find a 'plastic' bottle that doesn't work...pop bottles included. I've tried several different bottles and have not yet found a problem with interaction between the alky and the plastic. To me, then, the important factors are strength and leak proof.

My favorites are recylced contact lens bottles. They run from 1oz to 12oz, are near indestructible and, have fine nozzle tips which are great for measuring the fuel or pouring it straight into the stove.
