I am replacing my 40 year old Skill 7-1/2" handheld circular saw (it still worked but I gave it away!). Prefer a corded saw over cordless. I see the pricing all over the place and am wondering if there is that much difference between the new Skill saw for around $40 and the Dewalt for around $140. It isn't that price is not an option but I would rather have a tool that will last and work well. Thoughts?
