no contact equipment is cheap- dogwalks, Aframes, teeters and tables all cost money.
this
site has some affordable stuff but the most affordable way to get something is to buy the frame part and put your own plywood or other surface on it.
I own no contact equipment at all- all I have are jumps, weaves and tunnels.
we have a board that we work 2on2off but that's all we do at home......
