I've used the HF ones, which are decent enough but tend to wear out pretty quick on metal, but they ARE dirt cheap...
I've had the best price over quality with, surprisingly, Craftsman blades. I buy them on sale, made in the USA, and I've used one blade to make over a hundred cuts on mild angle steel building carts to carry freezers on top with no oil and it still has good teeth on it, in fact I'm still using that same blade.
If there is no Sears near you just find any USA/German/Swedish blades and I don't think you'll have any complaints.
