Hi,
I also have an Elegante and can relate to your table problem. I bought a big sturdy conference table from an office supply store, it's wood grain with stainless legs and it's so sturdy I could dance on it. I love it! Doesn't vibrate or wiggle at all when my Elegante is embroidering full speed. I have a sewing room in my basement and had the room for this bigger table. I have an Ellure and had an Esante and I could embroider on them on the white folding tables with not problem, but when I got my Elegante the table wasn't sturdy enough for the big machine.
It was a couple hundred dollars to buy, but it's like 5 ft. long and 30 inches wide, and like I said, sturdy as can be. I have room for my machine plus supplies and my laptop on it.
Hope this helps...
Bev
