Voltex is in my backyard and they make some of the best HeNe supplies you can get in my opinion, but they are very expensive. They actually make a rather unique universal power supply for HeNes, which I actually have been planning on doing a review of, but it's not here yet. I've used one of their older ones, and their newer one I've been wanting one of for a while. Very expensive supply though, but worth it for niche people like me that have tons of tubes of all types and sizes, or that make and test their own, etc. they're used on production benches to test their tubes and make sure they run as they should at a few places.
As for my oranges, yes, I love 612. I wish it wasn't so darn hard to get though. I have several oranges for research purposes, as well as fun. They're not really all that practical of a laser, and few have ever worked as intended due to how hard they are to make relative to the other colors. There's just so much that uniquely has to go right to get orange and only orange out of a tube. They almost never worked right or were able to be produced consistantly and reliably, and they don't really do anything that the other colors can't do better, and they're very gain limited if you don't want any invasive other wavelengths, even if your production is good, so they died in industry fast.
