Best CSAs to Join for Delivery, Variety, and Savings?

Currently live in Cambridge and was hoping to join a CSA that delivers as I don't have a car. Does anybody have any that they recommend? I saw a massive list on Edible Boston and was thinking of doing Family Dinner since it does delivery, offers a variety of goods (meat, veggies, grains) and seems to be a good price point. Has anybody tried them or would recommend a different CSA that offers better benefits?
