The FPU costs ~$20* but when I order it from the US transport and import tax doubles (Or more) the price. I just send sales@Micromega a mail if they know a local reseller in the Netherlands. Or how to solve it otherwise. It would be great to have this one in shield form, with SPI and a free to choose pin for chip select.
If you can't find a reasonable-cost solution, e-mail to exchange addresses, buy online, and have it shipped to me. I'll re-mail it to you (as a "gift") and you can reimburse my mailing cost to my PayPal account.
Doing business with US companies should not be this difficult.

the companies are not the difficult part 
I'll keep your offer in mind.
Ok - as for the shield, I think you can download a free version of EagleCAD (http://www.cadsoftusa.com/) to design, and (elsewhere) get PCB's made in very small quantities for less than $10/board.
if you go this route, and aren't familiar with EagleCAD, there are some excellent training tutorials on YouTube (I've been working my way through those in my spare time). See Cadsoft EagleCad Tutorial Lesson 1 - YouTube
or use one of these - Adafruit Proto Shield for Arduino Kit [v.5] : ID 51 : $15.00 : Adafruit Industries, Unique & fun DIY electronics and kits - or - Arduino Playground - Protoshield - (brd file included
or - http://www.nuelectronics.com/estore/index.php?main_page=product_info&cPath=1&products_id=3 - ~$8 cannot design them for that price ...
