I don't know about the Gidget tables, but for the Sew-Ezi, you would probably have to order the extra support to make it stable and steady enough. Since you don't need the machine to set down in the table, have you thought about just buying one of the metal all purpose tables from Office Depot (if they still carry them) or a used office furniture outlet? I have several I bought back in the day from an used office furniture outlet and they last forever and are very steady. I think I paid $20 each for them. The catch is that you have to get the metal ones with the laminated top. The new lightweight ones with the molded plastic tops probably won't work for you, thus I suggested a used office furniture outlet.
