norcal brewing has a special on 10" false bottoms. They were a bulk order he made for a different vendor so they are 18 gauge steel instead of the normal 16 gague steel and the holes are 1/32 of an inch larger than normal at 1/8 of an inch. They are only $5.99 plus shipping. For that price I will test one out and see if it works for what I need and if it doesn't I will order one of their standard false bottoms.
