Two hundred for skis with bindings is pretty tough. Also, I see you're in Washington St., so some of the wimpier/cheaper park skis (Silencer) would really get pushed around, you need something substantial. PE is a decent choice (you could go even fatter), but it's not easy to find with bindings for $200.
In addition to e-bay and craig's list, check Play it Again Sports if you have one nearby (they buy and sell used skis). Sometimes you can get lucky there (sometimes...).
Finally, I haven't used them, so I can't personally recommend, but skitruck.com appears to have some decent deals on used ski packages. I have purchased used gear from the evogear.com outlet (kids ski boots and a pair of kids skis with demo bindings) and I can say that the stuff I purchased was in at least as-advertised condition, if not better. Evogear's outlet may be outside your price range for used skis with bindings.
