I hope you realize that those guys were joking about the Look P18s. At your weight, you can't use those bindings safely. You need a 10 or 12 din binding at most.
These are some of the better ones IMO:
Marker Griffon
Marker Griffon Schizo
Salomon STH 12
Rossignol FKS 120
Look P12
(these are in no particular order btw)
You could probably get away with a pair of Salomon Z10s or Z12s if your really looking to save some cash, but I would definitely recommend one of the pairs listed above if you (or your parents, lol) can afford it.
