Bosch MUM 406070 Universal Mixer, $5

When it comes to consumer mixers and food processors, the Bosch MUM series is one of your most profitable profiles. There are newer models than the 406070, and you should learn to spot them too. But even these older examples can sell for hundreds on eBay, so you're advised to learn as much as you can about how to spot these machines!

Heck, I wish I could say more about this unit, but I'm at a loss here. When it comes to the stuff you're likely to run across, the Bosch name will be more commonly associated with power tools than anything else. So, seeing it on a piece of food processing equipment should really get your attention! Bosch can often mean high quality and high price.

Whenever you see any piece of equipment like this MUM, the first thing you should do (if you're thinking of buying it, that is...) is to check the condition. No matter how nice and expensicve a machine may be, few people will want one that's been abused, broken or worn out. Look for examples that look to have seen little use, as does ours here, and you stand the best chance to make money.

In general, parts and pieces to these little kitchen food processing machines tend to get lost or misplaced around the kitchen. And you can bet that when yard sale time rolls around, and the machine is put out in the driveway for sale, few sellers are going to scour their home looking for any parts that may be missingh from a machine they plan to sell for five bucks! So, it's up to you to do your best to make sure as much is there as you can get. And by all means, never hesitate to ask the seller if everything is there! Heck, it's their machine, so they should know, right? And don't be shy about asking them to go inside and dig up any missing parts or pieces they notice are missing. Remember, we're talking about your profit here!
