I, like Randy, have a Hegner and an Ex. All he says is true. I love cutting with the Hegner, but I cannot do the portrait type work with it that I can do with the Ex. I have never successfully been able to us anything smaller than a #3 blade in mine. I have not had the Hegner long and I am sure I will figure out how to use the smaller blades on it eventually. That being said, I really enjoy cutting thicker stuff with it. It is a workhorse. And it just purrs. I know my Grandkids, even my Great Grandkids, will enjoy using it someday.
For my type if scrolling I am a bottom feeder. I have not been successful feeding a #0/3 spiral blade down through a #70 drilled hole. It is going against the direction of the saw teeth and, well, I find it most difficult.
I will say of all the saws I have owned, I like the Ex the best over all. Tilting table versa tilting head means nothing to me. either way works for me probably because I so rarely cut that way. The Ex is just a great machine for the type of work I am now into.
Are the Hegner/Hawk worth as much more as the asking price over other saws,,,, hummm, well they are heavier built, and will out last the others, but no, if I had it to do over, I would have two Excaliburs instead of a Hegner/Excalibur set up.
