I'm not aware of anyone is ready with a buy it now solution since they've only sent out sample chips, to get designs like the Klondike tested.
I pre-ordered mine as someone from the UK, via this group buy (
https://bitcointalk.org/index.php?topic=200067.0), but I'm not aware their being any space left for any more buy ins for the chips anymore.
Best of luck, there was a few Europe based chip buys 2 months back, when I was doing it, however most of them are complete now.
Your options will be limited to buying up what chips you can now and get them completed via a Europe based assembler (
http://www.minerfactory.com/index.php/miners/klondike.html) as I've used as they do accept chips bought outside of their group buys.
OR
Wait for the completed options, which come out later, which you will pay a mark up price for and also be later before you get a working device mining for you most likely.
As a small note there is a UK based company who has made mentions of entering the market with ASIC based products, Enterpoint, but their goal is to make really really large multi-chip designs, so expectations is it to be expensive. But they generally only sell once it's ready to be sold, no pre-order non-sense.
