So I would buy a heavy-duty workbench that is height-adjustable, so that a machine can fit underneath and one on top. There are even some with wheels (but I wouldn’t recommend that). If you want, you can also buy drawers as an add-on (Thanks to the modular design!) etc. and then assemble them as you wish. Under no circumstances get it from a hardware store, but from industrial supply online. There are companies like Rau, Stier, Anke...It costs between 400 and 1000€. You can then pass these things down as an inheritance, and the heir will still appreciate the heavy quality (partly 80 kg *g*). No "Untergestell Mara" with its rip-off price can compete with that :)
