careful...while I don't disagree with this, and understand what you mean, very few people need 16 DIN bindings...

Once you've read that, you'll be better off.
As far as what good park bindings are, it depends on what you're looking for...
lightweight bindings: basically bindings that are nice and light, but not necessarily durable
- Salomon STH 12 and 14 (non-driver)
- Marker Squire and Griffon
- Head Mojo/Tyrolia Peak/4FRNT Deadbolt 12 and 14
nice and durable bindings: for people that destroy bindings on a regular basis
- Rossignol FKS (aka Look Pivot) 140, 155, 180 and 185 (you could put FKS 120s in this list, but that's debatable)
- Salomon STH 14 and 16 (driver toe)
- Look PX 14, 15 and 18 (I personally disagree with these, I've broken each of them, but people do swear by them)
- Head Mojo/Tyrolia Peak/ 4FRNT Deadbolt 18
Please notice that most of the "durable" bindings are high DIN and aren't recommended for most people, and most of the lightweight bindings will break fairly easily under certain park stresses.
That being said, I only trust FKS 155, FKS 180/185 and STH 16s on my park skis - I've very particular of these because I don't mind their weight (they're not that heavy in my opinion) and I've never broken them, while I have broken most of the rest of ones I mentioned. Again, this is me personally, and doesn't mean that they're necessarily the best for you.
