We have one like it with only 1 hanging pantry in the center and no sink. We bought it last year at Sam's Club for $53. Not all Sam's Club store stock them. We went to 2 stores before finding one.
We use an electric hot plate and rice cooker on it and have not had any problems. The frame work is very sturdy but I can see where the table top material could deteriorate over time if left exposed to the elements.
It also came with the carrying bag.
BTW,...The center table top is removable so I'm thinking the sink could be purchased and put in it's place.
Below is a photo of it
