A couple of things here:
When on a retreat we have 2 people share a long table. Each person faces the other but we take opposite ends so that our machines are over the table legs and our work is able to spread out onto the central area of the table. This way our machines don't bounce all over but are stable.
Yes, the Sew EZ tables are good. Just $$.
Since Sew EZ isn't in my budget I now use a small 2 ft x approx 18" Lifetime 3 height adjustable folding table. I take this when I am working at someone else's home. I actually have 2 of these so if I have a larger project I have extra room. I like the 3 heights available. Last I looked the office supply stores still sold them [Office Max, etc, ?Walmart?] and a friend found her tables at either Costco or Sam's Club.
