Hi this Honda GX270 powered pressure washer is available for me to purchase at around £700 is it a bargin? there is no manual so I dont know what the specifications are, psi or hp also what type of pump it is running on, if anyone has any info on this model I would be grateful, is it worth its money? also with it a lance with various coulerd jets & a 10mtr hose, would I need a turbo nozzle for it or a new lance?
