my ironing surface is 24 x 55 and that is sure nice to be able to iron a full width of fabric!
I think this one looks really nice, but would want to find reviews as to how stable it is if you are ironing on one end, or dragging something heavy around on top (Mine is a board mounted to a clip in the wall, so it's never going anywhere unless I take it down). I have a tendency to stack fabric on the end of mine, or that is where my cat likes to sit.
I use to have a oversized regular board, but kept knocking my iron off by putting it way on the edge as I was laying out pieces, and then I'd move and bump into the board and the iron would end up on the floor.
