I really like my Dewalt and have had it for about 5 years and use it a lot. A month or so ago I saw grizzly had it with the helical head for I think $1050. Don't see it now. I buy my blades from China for about $25. Been real happy with them. Can buy a lot of blades for the cost of the head. I've heard the helical head is a lot quieter which would be a good thing.
