I just tasted Freddy's gelato for the first time this past weekend and it was very good. I'd say it's worth the ride.
You also might want to include Mario & Gino's on Roscoe. They do not make their own, but they stock al Gelato brand which is made in Franklin Park. (Also stocked by L'Appetitio delis and a few restaurants). I love the chocolate chip flavor. (Mario & Gino's also stocks Double Rainbow ice cream).
The Penguin is well documented on this board and quite a nice little place to visit. One of the things that is often mentioned is that you need to do ample tasting at the Penguin to see "what's good today". Often times, many of their flavors can get gritty or icy.
