Well I have to agree with a lot of what you say, I do not doubt that the Hawk will last longer, I would love to give one a try. I also know my Hegner will out last me and whoever inherits it and maybe their children. But I do feel the Ex, will also out last a DeWalt. At least I read of far more problems with the DeWalt than I heard of about the the Ex's. I have owned both, I sold the Dewalt after I had it a couple year because I read of so many problems I had heard of and mine was starting to deteriorate. Make noises, losing tension. I had my Ex longer with no problems what so ever and I used it far more than I did the DeWalt. And a person should be able to expect that, the Ex cost a lot more than the Dewalt did. And I certainly would expect a Hawk to be better made than a Seyco or Ex. They are another step up. But I do not think they are that much smoother running. (keep in mind, I have never even sat at one) my Ex was a fine, fine running machine . The Hawk is a little more manual as far as changing blades, as is my Hegner. But the Hawk is also around 1/3 more.... $929 for the Seyco verses $1400+ $150 shipping for the Hawk. I am 73, do I really want to spend that much more just to have a saw that out lives me. I think my Ex, taken good care of would out live me, maybe a DeWalt also,,,, darn that is depressing,,, time for another wine. The Ex and hopefully the Seyco are easier to use when it comes to delicate fret work, I know this for a fact. You can not convince me otherwise. That is what I do most and probably always will do most. When I do heavier cuts, compound cutting, thick wood, I sit in front of the Hegner. Well not entirely true I do a lot of Fret work on my Hegner also. I usually have one blade in the Heg and another in the Ex and I switch back and forth. Less blade changes that way.
But I rattle on. I enjoy the discussion, please do not be offended by what I write. It is just a discussion. I will not get into the discussion about American made verses foreign made. That is a whole neither argument, that could go on forever. I do know the world is very small anymore and we have to step up to that....
Okay this is just all my opinion which is worth you know what. I sold my Ex, yesterday, not sure why other than I like to change saws like I use to like to change cars. I have my name in for a Seyco. Not positive I will follow through with it, may wait a while, may just get by with one saw, my Hegner. Who knows.
