to me it is not worth it.. realistically it is not really too expensive to buy a couple cycles.. find a good ugl and get it from them. The only reason I could see spending the time making it is if you were going to try and sell a bunch. Trust me I a a "Mcguyver" and love to try and see if I can do things.. like for instance brewing my own gear.. the problem is.. it is my body! if something is not sterile or I screw something up.. NO GOOD to me it is not worth it. a good UGL has spend hundreds of thousands of dollars making sure that does not happen. let them keep doing it
