Hey, what's the waist width of the Boone skis that you're trying to throw these on? I ask, because you could get a set of PX 12 Racing bindings that don't have any lifter, they use the stock Look toe-piece, but have the beefier race heel. The problem is that it's wicked hard to find the wide brake for the race heel, but you could always have the brakes bent. $119 is under your price range though.
There are versions that come with the full race toe, heel, and a wide brake, but you're looking at a DIN of 8-15 and a price tag around $190.
Hope this helps.
