In the photo below I have a small platform rack that Nashbar used to make, perhaps they still do? Sunlite made a similar rack too. Those mounted on the canti brake posts, which if your bike is a disc brake bike, you do not have. And a Tubus Ergo low rider rack.
Previously I had a Surly front rack but really did not like the Surly, donated it to a charity when I bought the Tubus rack to replace it.
Advantage to two racks is if you do not use one much, you can take it off and retain the other. I usually do not keep my low rider racks on a bike when I get home from a tour, put them on for the next tour.
