B&Q no, i definately would not as these will not last & the warranty is invalid if it looks used.
Ipurchased a mower for a spare on gardening contract & it fell to pieces in less than 6 months.
Get a good honda, i purchased a 5.5hp almost new with extra kit for £300.
Hardly use it but it starts everytime & has the power to do any job (small). Looking to take on more of this sort of work aswell.
