You will probably find that 6' plastic table "bowing" after using it for awhile. Having a table surface that is level with your machine makes a HUGE difference in not only your sewing but also your shoulder/back/neck pain. Cabinets take up a lot of space but they're worth it. There's also custom made (to fit your machine) acrylic "tables" that level the sewing area and they're portable. They come in several different outer sizes.
