I have a couple of Jandd racks I've bought from the specials section of their website - definitely under $50 and they work fine. I like my Tubus and Nitto racks better, and they are certainly more sturdy, but if you want to spend less they're not an option. Of course, if you're spending the money on a new Double Cross build, maybe you want to have a little nicer rack...just my thought, though. Just about any of the racks mentioned in this thread should be enough for commuting and groceries.
