For the Ruby, you could use any table or desk. Because its one of those embroidery machines that you don't have to take the arm off to sew I normally left it on so it would be a pain to have it inset. I now have a Diamond Deluxe and the same goes, since you can park the arm when you sew I never take the arm off. I'm assuming you do use the embroidery part as well. I'm still amazed at the number of people on here alone that have said they dont use it. The first promise I made to myself when I spent out that kind of money was I was going to learn and use it. I did for the Ruby and still do for my Diamond. I've even started FMQ with the diamond since its so easy. Decide if you want to keep your machine with arm intact most of the time or take the arm off and use it that way. It will help decide what size of desk you need to have.
