S.A.
we're looking into Walmart versions right now, and they seem to be much more reasonably priced. Also Lowe's or Home Depot have component parts that you can put together, but the kits are also pretty expensive in the end. But probably still a little cheaper than the $1-2k ones. What we do first is always shop on Craig's List and Freecycle to see if we can find something local and cheap or free!!
