why not take the unit and store most things like vases etc at home in your garage. I know a lot of little shops tend to keep quite a lot of stock outside so this could be an answer. If the location is right i would consider that the decision maker for you. Good luck in whatever you decide. My shop is really big and although on the plus side this is great for space etc, its also really expensive to keep stocked up

So, at least you wouldnt have that to worry abuot.
