When I looked into it, a torch booster was way too pricey and anyway no one knew about it here in small town, Arizona. You would want to find out if you have anyone in the area who could even order it and install it for you. You might have to order it for them. Look at the specs for some idea of the BTU. The gas company in your area would be a good place to check if the booster can be used, there can be a lot of local rules about residential gas modifications.

I was thinking that natural gas without a booster would work fine on an alpha, cricket or minor which are smaller torches. But you might be limited as to the types of glass you could melt. I'm not sure silver glass would turn out as well.

And of course none of that matters if you want to do boro and/or a bigger torch, you would definitely need a booster if you tried to run them on natural gas. But it's still $$$ to buy and install, so I would say it would take you a long time to see any savings. You are not paying a bad price for refills now (I'm paying $22)....oxygen is Waaaaaay more expensive and the thing IMO to invest in a system for. Look at doing a nice homefill system. It's the only way I would ever do a lot of boro. My little oxycons are not sufficient and I would burn through a tank so quickly! So that would definitely be worth the time and expense. Propane, not so much.
