I purchased a big board at a quilt show and love it :) . I also purchased the cutting board that covers half. So when quilting, I have a space to cut and a space to iron. I agree with basic woodworking skills someone can make one specific to the size of what you want it.
I do have a flimsy ironing board, and it works. But I am converting a spare bedroom into sewing room since I rarely have guests and will look to find a dresser/cabinet that I can set it on at the right height to make it more stable.
