In the end I went with Sany SY16C and it arrives Thursday. I am still trying to muster up the courage to tell the other half 😂 she just doesn't understand!
I have been thinking about all of the jobs that I will need a small machine for to build the house and it's loads. I currently have a skip which is due to be returned soon, and there is a pile of wood and a tree stump. No chance I can lift it in by hand. Even though the hire of a 3 ton machine was only £280/week, by the time I factored in the £55 charge each way for delivery and collection and the VAT. You are suddenly at £500 for a weeks hire.
I am also contemplating a one ton dumper, but I think I may wait before having that conversation.
