A real legally binding NDA is quite an hassle, I wouldn't even consider (any more) signing such a document if you didn't pay up front a substantial amount of money, in advance, regardless of the outcome of the negotiations.

If anyone is going to sign that is either a noob, or someone who wants to cheat you anyway.
The opposite is true too: if anyone asks you to sign an NDA without realising this, is himself a noob or wants to cheat you.

(of course if that NDA is not really legally binding, then it's just wasted paper anyway)
