I am looking into this myself (but only doing business in The Netherlands) and this seems to be one of the best solutions. For my purposes anyway.

For Dutch businesses: Ogone supports iDEAL and I think their transaction overhead is actually lower than when you do business with iDEAL directly.
Also, any chance you could elaborate on, or perhaps email me tav@espians.com on the general pricing?
As to pricing, it depends on your transaction volume. The only link I can find is in Dutch but it's relatively straight-forward (and maybe Google Translate can help you out).
Paul, our programmer who handles our payment gateway stuff, wrote a Python interface to the iDEAL API by Mollie.nl for use in Django projects. We also have our own transaction system, as we are dealing with donations, not your normal purchases. So we ended up rolling our own.
We're based in the UK and use Worldpay and Protx (as well a PayPal and Google Checkout)
