Good morning
I agree that most commercially produced machines are indeed "Over Priced". If you are at all interested, let me know and give me your email address and I will send you plans and complete instructions for building a machine for less than $100 dollars. Could be a few dollars more if you do not have a reasonably priced machine shop to stamp out the 2 inch diameter 316L stainless steel plates. All of the other materials are inexpensively available at a plumbing supply or hardware store and the rest on eBay. I have to leave for a doctors appointment right now, but I will photo one of the machines I built and post it either later today or first thing tomorrow.
