Selling on Agon question

Hi, I have an ad out, and someone with no feedback, from Mexico City, has expressed interest.

I am slightly wary, are there precautions I could take to ensure I don't get burned?

I was thinking:

-Insist on bank check/money order, wait for funds to clear before shipping.

-Ship UPS and choose the option to have the buyer have to sign for the item

Does that cover me?

I am wary of accepting paypal for this transaction as disputes usually go to the buyer, and this person could claim the item was damaged and ask for money back or something like that.

Any thoughts based on your experience would be much appreciated.
