I have the first one you posted. It works well. Perhaps not the greatest quality but it works!! For the price I would go with the shelf. A word of warning. Never ever move the table without unlocking the wheels. I moved my table without unlocking a wheel and it broke right off. So now I have to wedge into place when I move it. The cool thing about this table is it folds up to a convenient size. My quilt room is our guest room so it's great being able to make everything compact. If space is a problem for you I recommend this.
