Dutch iDeal will be rolled out continent wide pretty soon ( soon in bank time ), which is what you want.

Last time I checked instant sepa (which was today) it was free as in zero commissions on either side and was actually instant.

Depends on the bank. In Germany, N26's free account charges 0.49€ per instant SEPA transfer, and sometimes it's unavailable because the other bank (e.g. one used by many German doctors) only supports non-instant SEPA.

But yes, instant SEPA is often free and often available and very nice when both of those are true.
