You can find new Tyrolia ambitions pretty cheap. They have a better walk and ski mode than most frame bindings.
Do your boots have tech fittings?
If so, keep looking at TGR, geartrade, and used sections at cripple creek.com, skimo.com.
remember dynafit is rebranded by lots of companies, Fischer and Look among others. ATK is rebranded by quite a few as well, notably Hagan and Black diamond.
So make sure you just look for touring bindings, not a certain brand.
New/demo bindings start around $380. Doing that, might be better than saving $100 on a used pair. Then you can buy them from a good shop and have them mount them.

For skins, most skins list around $200, but again, finding something that fits, on closeout, is doable. Even more than bindings, skins are labeled with ski brands names, but are really only made by about 4 factories. As long as they don't have a proprietary attachment system, there is no reason you can't use them on any other brand ski. These 'ski branded' are more often found on sale than their regular ones from the manufacturer. I got some "la Sportiva" skins that way.
If you want cheap at full retail,

I would spend a bit more for some mohair/nylon mix skins.
Make sure the skins are wide enough for your skis, although you have a little leeway (I.e. if your ski tips are 138mm, a 130mm skin will still be fine)
