I have one that my father paid 450 for and got sick of storing it. Its a core areator, and I will say, it needs to be very, very wet for me to use it in my heavy ground. Weighted up or not. If you had lighter ground it would be good.
I can take pictures of what I have for comparison if needed. Or you can ask anything you want.
