Some guy wants my ipad 2 plus $200 for his 16gb 4s. Is that a ripoff on my end?
I sell iPhone's for a living. Depending on the carrier you are looking at between 275.00 for a CDMA iPhone 4S 16GB or 325.00-350.00 for a GSM/factory unlocked iPhone 4S 16GB.
If the iPad is wifi only it's worth about $250-300, and maybe about $25 more if it has 3G capabilities.
You are looking at an even trade at most, I wouldn't give him a dime on top of the trade.
