Have a look at this series of posts we wrote on our blog: http://blog.handcraft.com/2011/01/looking-back-on-the-quest-... - we looked at Fastspring, Chargify and Spreedly and ultimately settled on Spreedly and Ogone (and a merchant account with AmEx). Spreedly is the processor most like Stripe of the above list.

We're in the Netherlands (like you?). Hit me up on twitter or our blog if you need any more info.
