Depends on what kind of table, style, quality and $available. I like melamine laminate bookshelves to store fabric; it's not touching a surface that might change the fabric over time. I bought mine at Home Depot and Lowes.
For machine tables I have a Horn cabinet with drawers (storage), SewEz (great for taking..), and a 4 ft folding table. The machine fits down into the cabinet on Horn and SewEz. The Bernina 830 fits on top of the folding table with the embroidery attached.
These work for me...... Others have much different set ups that work for them....
