Well folks, I decided to pursue this, and am now convinced this is a scam.
The "Seller" wrote back accepting my decision to buy, and said she needed my full name and contact details. She explained that the transaction would go through EBay, allowing me a 3 day examination period of the Goods, and an option to return the goods if I was not satisfied.
I sent her my name and address.
Well I just got an email, advising me that a "Transaction Agent" would be the Intermediary.
She advised I should send a "moneygram" (an emoney transfer) for $1500 to the Agent, a man's name and address in London, UK. The "Seller" noted is a woman's name, address in White Falls, MT, USA.
None of the EBay or other links on the email work, and one is invited to contact the seller with any questions.
