I pay $140 for an 8-week season at my CSA. I bought the couples share since my 2 teenage daughters can be picky about what fruits and veggies they eat. It's always plenty of produce for the three of us. I also only do the early and mid season since my girls don't really care for fall produce. Here's a sample of what we get (taken straight from the CSA website:
Early Season - Choice of fruit (ie. strawberries, cherries, peaches), 3 lbs vegetables, you-pick, (ie. tomatoes, squash/zucchini, potatoes, onions, cucumbers), 4 bunched items, you-pick (ie. asparagus, carrots, arugula, lettuce, spinach, beets)
Mid Season - 5 lb basket of fruit, you-pick (ie. peaches, donut peaches, plums, nectarines), 5 lbs vegetables, you-pick, (ie. tomatoes, squash/zucchini, potatoes, onions, cucumbers, peppers, eggplant), Pick 2 other items (ie. corn, melon, heirloom or cherry tomatoes, beans, blueberries/blackberries)
