LoL I have 22 disposal's now 1950s-2000s Waste kings,Old Maytag's Fc-10 and Fb-20,Old G.E.,Kitchenaids/Hobart,National,Elkays,Sinkmaster,I,S,E, E.T.C. I have always been fascinated by them and I don't have the room for more than a few dishwasher's and washer's. I can't use these disposer's out today cause they grind so coarse.The Evolution excel I can use but it is slow at grinding but vastly better than there others they have.Old Maytag's are my Favorite and I have two of those and it took me years just to find one.That FC-10 one of two on ebay I got but the bidding went up to 525 bucks for it.I did not care the last one went for over 600 bucks..I am using a 1970 Waste king SS8000 it is a great disposer huge machine and the price on the box was 299 in 1970 that is a ton of money for then.The other one is a Batchfeed 1985 Kitchen aid which is another great one.These old Machines have cast alloy grind rings and real blades in them and under cutters and will grind anything.
