OCD makes about the most inexpensive pyrex tank I've seen. $5 for a clear glass tube and $19 for the ss caps, which are available in 3 finishes. Pretty solid value for the price and look nice. They also do custom painted tubes which are rather unique. Check those out.

Siam Mods makes a slim pyrex tube tank with either titanium ($35)or stainless 9$25) endcaps, that even have the trademark Provari dimples on the side. Not the quality of a Pro V cartomator, but not the same price either. I've wondered if their glass tubes would matchup with the Pro V's endcaps to replace its polycarbonate tube.
The glass tubes are available in clear, frosted, blue, and green - $15

This is a forum member who does artsy pyrex tubes. No website, must PM her for an inquiry. I believe she now sells metal endcaps to go with her tubes.
Of course, there are the
Smoktek DCT tanks with the metal endcaps that are the perfect diameter for the Provari. Available from nearly every major vendor. The newer versions have the frosted polypropylene tubes.
I know you're looking for a chrome metal-capped tank, but I just saw these when on the Clouds of Vapor site and thought it might be an alternative to the Vivi Nova and Smoktek Titan clearo tanks, rebuildable and for $20.
