LOL! I'm not sure how many times I've seen that sewingmates table and it never once occurred to me that it was adjustable of all machines. I've been thinking I could lower a table, and then recess something like that. I would love to know what you think of the tables in person. I could order one I suppose, once I save up a little more cash.
In the meantime, I've picked up an old computer table out of the government surplus, doodled an outline of every machine I have on the top of it, and cut a hole to accommodate them all. I have Lexan waiting in the wings for me to cut it. I just have to "get to it". I was supposed to do it this weekend, but then I got distracted by reorganizing the sewing / machine shop room, and buying another machine.
