This is so ironic. I just completed an order with ASW (an art supply warehouse). They had their carts, (like the first on you posted), on sale for $39.98. I think this will serve my needs O.K. I do a lot of painting away from home and can't always be sure of a chair so this answered my problem. These carts in other stores were $79.00 and I was waiting trying to find a better deal.
I like the rolling potty chair also. It actually looks like an air conditioner.
Off to the mall I am going.
