Unless you have money to throw around, just use the bindings you have. I get the feeling you don't have the experience to know exactly what you want, hell you got sold on a skate banana.
Ride the fucker with the bindings you got for like 20 days. If you don't like em, you will know why and what to look for when you shop.
Yikes, I'm afraid to ask why that was a bad decision.
