Gym Membership

I'm thinking of canceling my gym membership at the Chicago Sweat Shop and signing up at Pulse Fitness Center. As much as I try (and want to), I haven't gone to the Chicago Sweat Shop with any regularity for the past two years --yet I pay them about $60 a month in membership dues. So thinking about switching as Pulse Fitness offers a pay-as-you-go model. But I'm a little hesitant about making the switch because I'd be giving up access to all the classes offered at the Chicago Sweat Shop. So wondering, has anyone had any experience with these pay-as-you-go gyms? If so, I would be interested in learning more about your experience. If I really did start going to the gym on a regular basis, not sure that Pulse Fitness would be a good deal financially. However, I feel like I'm wasting money by maintaining my Chicago Sweat Shop membership. Talk about catch-22.
