Broken Kitchenaid Mixer... Repair or replacement?

This subject is a bit off topic, but it is often a subject I think about often when designing jewelry. Will it be a piece that can be repaired or will it have to be redone completely when something break? 

My stand-up Kitchenaid mixer had been leaking oil and right before Christmas it finally gave up completely and stop mid-mixing my cookie dough. I looked for someone, a shop, a repair person to fix it, but come up empty. Then I searched online for possibilities and found an online tutorial on how to fix it. It took me several month to finally get the courage to take the machine apart. Other than having to deal with the rotten grease, it was fairly easy.

And just as in the video, one of the gear - designed to fail - had failed. 

Then next I cleaned up the machine the best I could with old rags, Q-tips. Laid everything as neatly as I could so I could find all the parts again and placed an order online for the replacement parts: the gear, gasket and new grease - this time food quality grease, hoping it would smell better, which it did - thank you. 

Once all the parts arrived, it was time to put everything together. My brother-in-law's advice: if any part is left on the counter (the washing machine) when you put it back together, take it apart again... Ha, ha, ha... He must have ESP. The only problem I run into putting together was the five screws right under the motor. One screw out of 5 would not fit. After switching them around, switching the order I put them in, just placing them carefully in place and only giving the one turn each, one screw still would not get in, regardless of what I did. I gave up, put in 4 screws out of five and yes I was left with a part on my counter, one screw. 

Next come the ultimate test, did it all work - even with a missing screw? Yay - It works, I have a working machine again! 

To celebrate I made a traditional Swiss flourless carrot cake for a gluten-free guest. Let me know if you would like the recipe.
