Replying to WTB look px 12 binders

Hey, I need some new bindings and i think i have settled on the px 12s.

Anyone know where to get some inexpensively?

Any reason why i shouldn't want them?

Im 125 ish, and about 5'10. Im not the strongest skier, but im not by any means bad.

I need an upgrade to my marker caraptastic 10s.

oh... and mounting these on parks skis. not sure what yet tho.
