shop around the discount is ok, but the prices are really high to start out....
I've got a mix of cratsman snap on, matco, mac, s/k, proto, ingersol, and china specials from harbor freight
Start with a good basic set of hand and air tools and go from there... if you need to borrow it more than once go and buy it is my rule
the best thing about going with a truck over sears is the truck comes to you at least once a week and the guy usually knows his shit at sears you get stoned johnny highschool who makes minimum wage
I still buy from sears sometimes, but its rare anymore becuse its a hassle
