Looking for a lawn mower

[L.R.S.]

Anyone have a used lawn mower for sale?  Prefer to buy from someone here if possible.  I've checked NextDoor and Offer Up and they are all stupid electric mowers.  I want a gas mower.  Nothing fancy, not self propelled, just a basic mower with a grass catcher.  It'll get used twice a month on 700 sq/ft of yard.  My transportation business gets us all over the place so let me know.  I'm in Phoenix Wed to Fri and my son is in San Diego Thurs to Sun.
