Kobalt has rebranded Craftsmans, locking flex head ones. I think its an 8 piece set for $100. Made in USA. These are not the crappy coarse tooth ones, but with heads just like the Gearwrenches
Duralast is another good one for reversible non flexing wrenches, but I think they are just rebranded Gearwrench. Made in Taiwan instead of China. A 7 piece set for $50. I have a set of these in SAE, and will be getting a set in Metric soon.
I just saw some Master Mechanic ones at True Value. They are probably also rebranded Gearwrench. I didn't see a price on these. They're made in China.
Actual Gearwrench ones are coming way down in price now that they have moved to China. I have also read the quality is going down too. I don't have any to know for sure though.
