For methanol recovery, I bought one of those SaveVac 140 series from http://www.bestechind.com/product.htm Check the spec if it pulls enought vacuum for you. If it does, it is more cost evective to get it and not waist the time with the 'old clunkers' :)
I bargained with the guy, and he sold it to me for 169.
