ive got a great, absolubtely mint honda gx340 11hp with interpump 201 / gearbox, it's less then 3 months old and in as condition, they are around 1400 to buy new I would take £850 cash, complete with all hoses/suction filters etc, ready to work, has low pressure chemical feature with vario nozzle, may even throw a new turbo on too if your a nice bloke
This machine is more then capable of taking on any domestic job and most commercial should you get them, if you go for a cheaper less powerfull model then you will only find you will sell and end up buying something like this in the long run...
will hopefully be listing it on ebay sunday if I can get a nice dry day to take some pictures of it...
