Hey guys!
So my family isnt doing too well in terms of money right now and i want to buy a gaming compputer...those sentences never go together. Anyways, a couple days ago, I found an ad on craigslist where this guy was selling a $1500+ gaming pc for 1000 dollars OR partial trade for laptop. I want to trade my decent laptop because all he wants to do is surf the web, watch videos, movies, and general everyday stuff. As he says, he doesnt have time for gaming and drafting, which is what he bought the computer for.

My laptop specs are:
AMD Phenom II X2 N660
ATI Mobility Radeon HD 4250
320 GB HDD
4GB RAM

Its a pain trying to contact this guy, because he didnt put his phone number in the post or his personal email address. Now I'm stuck trying to contact him with his default craigslist email address. Yes, i have tried using that, but he hasnt been responding.
What should i do?
I was also wondering if there is anyway to get his ip or whatever from the post and then find his phone and/or email from it.
This is really bugging me, because, for once i can get something i want, but THIS happens.
