Carlos, I'm using shutterpoint.com. I was attracted initially because they were listed near the top in my google search. They basically rent you a certain amount of space for a very reasonable rate, they let you set your own prices, and they're easy to work with. They also have power raters, pros who will rate your photos, make suggestions for improvement, and the highly rated photos are shown on their front pages. I also like their statistical tabulations.
