Question about abs

I've lifted for the better part of a year but was never concerned about my stomach/abs. I finally have gotten to the point that they are what I care most about, but I don't really know how or where to start. I'm cutting about 1500 calories a day to see some weight loss, but what is best for working the abs of a beginner? Would something like AbRipperX or just plain crunches work best?
