Sorry guys, I forgot to subscribe to thread so I didn't noticed replies until today when @harvy sent me PM.
So, to answer your questions:
* 100 RPIs are in Croatia, EU
* All are new, just opened to put number marking on them
* I listed them on eBay but there was 0 interest so I didn't update the listing
* I can sell 10 in one lot (minimum)
* Price is (€26 per unit + shipping) * 4% PayPal fee
* Discount is possible for larger order, send me message
* Shipping price can be checked here http://www.posta.hr/default.aspx?izracun
but it's only in Croatian so it won't be of much use. Shipping to EU is about €10-€15 for 10 picese.
* you can check photos that show how we refurbished them to put number on every RPI here:
