Have you checked allbrands.com? The largest extention table they have 24 x 24 is $79.99 with free shipping in the US. Smaller sizes are less. I ordered two for Christmas, a larger size for one machine, and the junior size for the one I take to class using money I was given for Christmas. I have waited years to get these. I have been so impressed seeing others use these and their comments have all been favorable. I've ordered from this company in the past and never had a problem.
