My favored sewing table wouldn't work for you - my machines are regular size. Salvation Army often has empty cabinets. They say people only want the heads of vintage machines. So I buy one and retrofit the opening. My only free arm machine has a table that drops to access the free arm, but it isn't used much anymore. I used it heavily when setting sleeves in little girl's dresses. I have difficulty sewing unless the whole area is flat, but I think it's what you are used to. One of piecing machines is a portable. I never know what to do with the weight of the quilt as it grows.
