Keep your eyes peeled for a 3 or 4 drawer lateral file cabinet. Easy to add wheels and a larger work surface too. High capacity, sturdy, and can also be found for cheap/free on FB/Craigslist.
I have one in the background here. $20 on craigslist and the office building had 10 of them. 1 can of black paint, free Ikea table top, and (4) 1" wheels have me setup nicely. Very nice working height and can roll easily if needed.
