Concerning the skis, I know at least one person who isn't too hard on their equipment, and the suspects have been just fine.
Concerning the bindings, it could be hit or miss. If you get pretty good quickly, the bindings might give out. Then again, they may work just fine.
I had to learn the hard way, skis or bindings, you get what you paid for (unless you get some crazy good deal). It is always worth it, to me at least, to spend a little more and get slightly burlier gear. It doesn't sound like you can do too much about it now.
If i were you, I wouldn't be too worried about it, but just know that it MAY happen, as is the case with any skis, bindings.
If at first you don't succeed, failure may be your thing.
