My Hawk Model Number is 220, and it is a two-speed. I bought it cheap from someone who purchased it with a shop full of woodworking tools and never used it. I cleaned it up, replaced some parts, and upgraded everything I could. It worked well and considerably better than the AMT cast iron saw I used for years. A few things I don't like. The blade changes and making internal cuts are a pain. While it isn't a huge issue, I'm not too fond of aluminum tables and prefer steel or cast iron. This saw has exposed electrical connections under the bottom of the saw. I have been considering replacing it for a couple of years and would like to pick up another used EX21. However, good quality scroll saws are rare in the used market where I live.
