Just want to make sure that you understand that there really isn't any PayPal protection if you do an off-eBay transaction, no matter how reliable the seller is. It is my understand that many reliable sellers do transactions off-eBay because the buyer and seller and both comfortable doing it that way. It saves as lot of money in eBay final value fees and in PayPal fees.
From what I've read on this post, it sounds like many agree that you'd be best off trying to go through a boutique - at least that way you know the transaction will be safe and you will be receiving authentic merchandise of your choosing. Why don't you start with a bag that is neither a Kelly or a Birkin and establish a relationship with an SA. It should be easier then to ask for and get your Kelly or Birkin.
