Need a new rack

So I've broken some of the welds on the rack on the back of my commuter. I haul groceries with it, which can be a lot of weight when it's canned goods, and sometimes ride a little more aggressively than I should.





I'm pretty into most of the system - I love those wire baskets, and a single attachment to the brake bridge seems to be adequate, which is good since there aren't any chainstay mounts. I'm looking for recommendations for the rack itself. I'd like it to cost under $40, since this is a bike I leave locked outside from time to time.
