I am currently using two mowers both 21" self powered walk behinds. Prim mower is a Honda Harmony 215, purchased new about 14 years ago. Back up is a Toro electric start, I sort of inhearited from a neighbor who wanted something newer. I am a retired mechanical engineer and have a propensity for picking up old equipment others discard and returning it to useful service. Sometimes for my self and sometimes I sell them off.
