Granted this thing is accurate and well made (almost bomb proof) but why so heavy and bulky. I don't think it's necessary. I love porter cable products and have used them for years. My edge guide came as a freebie with a package deal I bought. I use it and  have no complaints about it other than it being just too big and heavy. If and When I buy a new edge guide it will be the porter cable model# 5043,it offers the same level of accuracy but without all the bulk. Now get out there and round something over.
