The racks I used were the Sunlite ones. I bought a few of them when they were something like $12. Here is a picture where I used a dry bag on the back with the sunlite rack instead of a seat bag. I used a bar roll on the front along with a little REI Flash 18 backpack in this case.
I find the Sunlite can be mounted with p-clamps when there are no canti bosses. I used double p-clamps once on a front mount with little plates for a heavier load on the front, but it is better with the canti bosses.
