Hi, sorry for my late answers. The board limits me to one message per 10 minutes. It think I should post a bit more.
Escrow and shipping is possible but extra. Shipping from germany is quite expensive out of europe, express is very expensive. (See DHL.de for rates)
At ebay a mini recently got away for 1667 € which means 1500 € per piece are fair. Therefore 6 BTC for all three are minimum.
At the moment they do > 0.04 BTC a day, so you get > 0.12 a day with all 3. After 50 days you get the ROI with current difficulty and with a 20% increase every 12 days it takes around 80 days. This is okay.
I only sell them because I got some more efficient devices and don't have enough electric power @ home.
I still prefer pickup, even tomorrow is possible.
Here is a picture of my mining rack.
