How much would a supply be Dr. R? It'd be nice to have a 30" globe 
full of xenon (or what ever is used for the TC-ground-arc white 
color), but at $9600 just for the globe everywhere I googled, a bit 
out of my price range for a few years. Hence the flask version, even 
tho just the 72L flask is nearly $1000. Kinda sucks everything on the 
biggish side and glass is expensive. Probably should learn to blow my own lol.
