I've put off this purchase for awhile now but I have a job coming up that having it on site on conjunction with a tracksaw would save me probably at least a full two man day. But I really don't see the advantage of that tilt arm protractor for standard cuts. It would seem it accomplishes nothing more than what qwas or parfit dogs can do. Also transporting it becomes much easier without the protractor to store. While the price of a smaller track is the same essentially as the track and protractor with the full kit, it seems the protractor would be relegated to a corner of the shop never to be seen again in my use. Any comments, am I missing something??
