I found what I think is a bargain at a chain store (whose name begins with "L") for only $39. It is about 5 and a half feet tall, shelves removable, cover is a removable plastic item with zippers, dimensions about 26 x 18, and wheels. It seems perfect for those plants which can outgrow shelf space. I don't want to do a commercial here, but a local feed store has the same item for $70. The cashier told me this items sells out very quickly.
