It sounds like you found a nice source for timber. Usually a little background helps in understanding the situation.

What have you been using to cut the timber?

I would not use the lower priced versions of the Mafell. I had a bolt on to a Skill worm drive which was nothing compared to the Mafell, I have not used a Mafell. This salesman sure makes it look fun.
