A UK firm called Level Developments has vials for sale. Contact them by email and ask for the current price of individual ground vials. They were $50 each a couple of years ago. The service was excelent and I had my vials in a week. Look under my name on this site for detailed instructions to make a metal base for the vial. You really only need one. I made two just for convenience and speed of set up.
