Be careful... I've had a lot of trouble with my Bezel's from Happ's. It's not their fault, but I overlooked quite a few things...
I wouldn't be too worried about the 25" being too big. If it is, just use regular scissors to cut away from the inside of the bezel. Their might be a better way than to use scissors though, but they seem to work fine on the plastic.
One big problem I ran into is that the 25" bezel fit my TV just fine, but the outside part of the bezel wasn't sized big enough so it left a LOT of my cabinet exposed. You might want to check on this before you get the bezel only to find it doesn't fit the cabinet.
By the way, I'm using LuSiD's design...
