http://sewingmates.com/ makes acrylic extension tables to fit sewing machines and offer EXCELLENT customer service! I ordered a table for my machine, but the back piece didn't fit against the back of the machine correctly. Becky told me to take a picture of the back of my machine with the measurements and they would make a piece to fit it. They sent the piece free of charge and told me to keep the wrong piece in case I ever needed it for a different machine! :)
I would also like to send kudos out for
http://www.aaaquilterssupply.com/index.html. I bought a backing fabric from them and they were able to ship it for less than the computer computed and then charged me only for the actual shipping, not the estimated (which I had already agreed to pay the estimated!) They have GREAT prices! I got my 108" backing for $7.50/yard! And it arrived in only 2 days from the time I ordered! :)
