there are certainly cheaper options if you're willing to wait just a bit longer for example OSH Park, $5 Sq/in for 3 copies 12 Day turn around.

Agreed. That is a good one.

I was thinking of more complex board, with non-standard finish and soldermask.

Even Pentalogix in Oregon offers 2-4 layer boards for about $25-$40 in two or three day turns.
