Sonicus,
Communication differences aside, it has been my experience that poorly worded responses to ads are typically scams.
As far as paypal goes, anyone (i.e. seller in most cases) who completes a transaction using paypal involving large sums of money is asking for trouble.
~1.5 years ago I sold some electronics items to someone, they paid using paypal. After about two months I get a notice from paypal saying the buyer never bought the items, and never had any contact with. Despite email correspondence I provided that proved otherwise, paypal proceeded with a chargeback against me. I was out almost 1k, and the items I sold.
Essentially it appears that as a seller you have no protection. All a buyer has to do is say they never recieved an item, or it showed up damaged or something and you could potentially be out your money and the item you sold.
If you google the phrase paypal+fraud you will find some very interesting reading.
OP, best of luck to your sale. I recomend a cash transaction in a well lit, populated place such as a bank as someone else suggested.
