I'll second Craftsman....had all my stuff for about 10 years. Snap-On would be the best, but I don't have that kind of dough to spend on tools. I'm starting to like some Kobalt stuff and like mentioned above, they have the warranty also.
Sears always runs sales on the tool sets. Also, you get great deals if you join the Craftsman Club....it's free. Sign up for email allerts and they send you good coupons.
