Don't do it, you are about to get scammed.

With PayPal I would never send anything valuable outside UK any more, possibly US/Aus/NZ if I used a reputable courier.

I sent something reasonably valuable to the US by Airsure, buyer claimed it wasn't received and I didn't have a signature (UK > US post has no signature option), so I was scammed. In your case all that needs to happen is that for whaetver reason you don't have a signature (flakey post/courier) and you lose the lot.

I am just about to sell a camera body and lens on eBay and don't plan to offer it to anybody outside the UK, I think there is a decent enough market here that the bidding will be good enough. Shipping will be by Special Delivery only, or cash on collection (no PayPal before collection).
