Thumper, personally I'd go for the new one over a used one, that is if you can afford it. I never liked buying someone else's problems, which is what you could be doing by buying a used one. The EX21, if you buy it, should be the last scroll saw that you'll need to purchase. I purchased one three years ago, and I am as happy today with my purchase as I was the day I bought it. I don't know what type of cutting your going to be doing, but, if your going to be cutting anything on an angle you definitely want the EX. A lot of people don't realize, just how much of an advantage it is to have the head tilt rather than table, the blade changes are about as easy as you can get. The saw runs oh so smoothly, and there's no vibration with the saw running. I may have a bit of a slanted opinion on the General or EX21 as we call them, simply because I own one, bur I'm basing my opinion on what I've used in the past to cut with. I went through two Delta scroll saws, and used a Dewalt for four or five months while waiting to save up enough money for my EX21. The Dewalt was a loaner from a friend, he didn't use it much, it was a descent saw, but, it's no General. And last if not least, the pride of ownership you feel every time you look at your new General, is priceless!
