I stop in at Herrell's everytime I'm in Northampton. Their ice cream is easily the best around. Although the lines can get long they move fairly quickly. The chocolate sprinkles made fresh in-store are amazing. They always have a great variety of flavors that constantly changes. My favorite is Purple Cow (black raspberry with white and milk chocolate chunks). The Smoosh-ins are also delicious. The prices are a bit high but worth it for the quality. Do yourself a favor and check out Herrell's.
