Parker Brand sell pretty decent cheap petrol chainsaws. I have a PB 20" 62cc unit and like other PB products( such as strimmers, leaf blowers and hedge trimmers) they have a extensive catalogue of spares from bolts and carbs to replacement engines so their is no reason that their products should not last a lifetime. I got my Ryobi 12" brushless a month ago and I love it. One thing you failed to mention is its fun to use and with a additional 9AH battery could do a days worth of logging easily.
