Tell them no, and that you'll be happy to talk to them providing they tell you no confidential information. Their response will give you a good idea of how much they want you. A good way of reading legal agreements is to assume that someone else will take over (ie it doesn't matter if the person you are talking to now is nice) and what that person could do if they had it in for you. It is extremely likely that the NDA is very one sided. If you really want to wind them up, ask them to pay for you to take the NDA to a lawyer to have it reviewed. After all if the NDA is that important, you should also treat it way. That said, I know several people who just sign them all without even reading them on the grounds they are unlikely to hold up (one sided) or be enforced.
