I do the same thing. I buy quality and then run them till they drop. Harvest yellow or avacado green? who cares?! it works! When I sold my last house I did upgrade the appliances, but only because it was on sale. I donated the old stuff to a nice family that needed them. 5 years later, and the donated stuff is still working, and the new stuff that I put in the house was upgraded not long after I sold it. new owners wanted stainless. sheesh! could have saved myself some money.
