I guess I am going to go with the 4 1/2 Dewalt. I do understand it would take around 6 "cheap" grinders to go bad to make the $90 grinder worth it. If anything that is 5 less trips to the store to buy new ones, /forums/images/graemlins/grin.gif that has to be worth the extra money right there.
Thanks EVERYONE for your input and help!
