I couldn't find one I liked, so I took a piece of board and made a slip on cover for it using that ironing board stuff you get by the yard from Nancy's or Joann's. To iron I lay it over one of those small lightweight rectangular fold up tables that they sell at Sam's. I'm short, so I can stand and iron at it comfortably, but it also is a good height for sitting and ironing (just a little lower than my sewing machine cabinet).
I used a scrap board so it's a little narrower than the table, but it is long enough that I can iron the entire 45" width of a piece of fabric on it. It's light enough that I can easily put it out of the way when I need the table for something else.
