Should I trade my iPhone 4s for a Macbook Pro?

To be clear, the iPhone is 32GB, 4S and is unlocked. It has 2 nice cases and 3 chargers, and I put an ad on Craigslist. Someone replied asking me if I would trade them for their 2007 Macbook Pro w/ a cover case, a carrying case, and a remote. They sent me a few pictures of it, and it looks really cool and like a great deal. However, I did a little research on it and it says that the Macbook Pro 2007 version is anywhere from $500-$900. I am questioning whether or not this is a scam, or just too good to be true. He did provide pictures, and we both clarified what we had so that part is clear. I just don't know if I should go through with it since it seems too good to be true. However,I wouldn't want to pass up on a great oppurtunity like this. Should I trade them across? Also, should I make a contract/bill? Also, where and how do I get one. Please provide full details. Thank you!
