For me the most important thing is having the bed of the table at the correct height. I learned to sew back in the day when there were no free arm machines, and do not 'need' a free arm to sew anything.
I have an adjustable height Ikea table and a Sauder sewing table. Neither was expensive nor take up too much room. Both have the bed of the machine at the correct level for me to sit and sew with out straining, my should, neck or back.
