Thanks everyone. I just upgraded my concentrators to the two Regalia's. I've been getting counseling from Mary K. She and I think alike when it comes to hauling oxygen tanks around. I have no desire to make anything larger than about 1.5" (and that would be a rarity). Currently I am able to melt the boro without too much patience, but the colors just aren't there. I've melted soft glass for about 10 years and do pretty well at it, but even there, I can't get the colors out of the soft glass that I see some others do. The only difference between Mary K's setup and mine is the NG. I may end up switching it back to NG, but for a couple hundred bucks, I gotta try and see if there is a difference.
Thanks for all the input and I will report back
