VEVOR offers 15 amps and a 16-inch path at $133, among the lowest prices for this width, and a listed 26.7 pounds is the lightest in the class.
What you do not get
The rating history is short at 101, and no warranty term is given. VEVOR is sold directly by Amazon.com here, which makes returns easier.
Safe use
Unplug the machine before changing a roller or clearing the tines, and use an outdoor-rated cord on a GFCI-protected outlet. Mark sprinkler heads and buried lines first: tines at working depth will catch them.
