If I was building a tool like this for sale, I'd try to find a stock 
(therefor relatively inexpensive) vial that was adequately precise, and 
specify the rest of the tool around that in hopes of producing something 
useful and still making a profit. If that's what Tom did, I wonder where he 
got his vials. There will be broken ones needing replacing, and no source 
for them.
