I've got a great deal on a MIG welder from Sears/ Craftsman. It came with a mickey mouse hand-held visor. I'd like to get a good one. What should I look for? For ones that say auto-darkening should I look for a number or some spec? Sujit -- Sujit Roy, Realtor Keller Williams Realty, Cupertino, CA (408) 839-8359 roysrealty.com
