Go for the biggest one you can afford and have space for. Ideally concrete onto a solid base (single row of bricks?) so it cannot shift in the wind and twist the frame out of shape. Glass is clearer and allows more light in but poly does have the advantages of being lighter to handle and less pront breakage. As much movable shelving as you can get made out of alsorts and you will have an extremely useful piece of garden equipment.
