If I were you (and you were as cheap as me), I would put a dab of Aquaseal or something on the outside of the little hole and not worry about the break between the teeth. As long as you dive with a buddy that can carefully zip you up, you shouldn't have a problem with it for awhile. I dove a suit like that for over a year (over 100 dives). The only problem I have with the break between the teeth is when I'm solo diving (95% of the time) and I have to zip myself up with a belt around a sign post or something. If the zipper gets caught on the protruding tooth and you keep pulling on it, it can pull the tooth loose. Then you're screwed. By the way, $80 for a drysuit! You must be made of money! I try not to pay more than $50.
