If you are targeting finnish traffic try to find processor who supports verified by visa system.
In Finland there are over 2 million issued visacards. More than half of them are nowdays visa electron cards and most of our debit cards cannot be processed online without vbv..
I have no personal experience with
http://www.oxbill.com/
but it seems that they support vbv
Maby you should try verotel also.. If i remember right verotel supports finnish language on their billing page...
