Bought the attached for £100. Used it yesterday and found it much easier that the traditional two handled and petrol varieties. Only done 10 minutes to prep for a row of spuds and still showed full power. No post tilling aches or pains, even with my very poorly back, and no need to walk on where you have just tilled. Much easier to control than petrol versions used.
Does not go as deep as some others but done a decent job and ideal for doing small a and regular jobs as no need to get petrol try and start and easy to transport.
