Dude, its EZ as writing 'A-B-C' to make your own. Cheap to build. Me, I've made 3-extractors this week, all different sizes. Cost: _none_. Used supplies around the house. In fact, IMHO, my most recent extractor is probably the best one I came across, & built. But each one I have works beyond great... Do a little research bro, you'll find a lot of places to make some of your own. Pz.
