I am buying it used coz its for someone else outside the country. If its not worth $150 then I won't buy it. i am not finding any 3gs and the ones that I find are overpriced.
150 is slightly high but not egregiously so. I sold my 3G for 100 but I probably could have gotten a little more for it. See if you can get him to settle for 125 but if it's in good condition and includes everything 150 isn't terrible.
