A good planetary mixer outlives most of the kitchen around it, which is exactly why the used market is full of them. The trick is buying the right capacity and confirming the gearbox is healthy.
Size it to your heaviest regular batch
Mixers are rated by bowl capacity (quarts) but the number that matters is how much of your stiffest dough they can handle. A 20-qt mixer that's perfect for cake batter may struggle with a full batch of bagel dough. Size up if you push heavy dough daily.
Run it through the gears under load
Run the mixer through every speed and listen for grinding or slipping — the gearbox is the costly failure point. A little noise is normal; grinding, or a machine that jumps out of gear, is not. If you can, mix a test batch to hear it under load.
Check the bowl lift or bowl-raising mechanism moves smoothly and locks, and that the safety guard interlock stops the machine when opened.
Attachments add or subtract real value
A mixer that comes with its bowl, and the flat beater, whip and dough hook, is worth noticeably more — replacement attachments aren't cheap. A #12 hub in good shape also lets you add a meat grinder or slicer down the road.
