I haven't done this in a while. Please refer to the second link in my previous post which I identify as "cost estimate".

The best places might be online at Amazon if you have free shipping, Harbor Freight, or a hardware/home improvement store.

Here is an estimate for the total use of the Bravo. I assume the outer flame of the Bravo would equal the total use minus the use for the Alpha. (I don't remember where I got this chart right now.)

OK, I hope you can read this because I can't put it in chart form without uploading an image, and I think the original document is too big. (Spaces and tabs are automatically removed.)
Note: I have left off everything for the Lynx except for the LPM.
Note 2: The numbers provided by the oxygen concentrators do not add up to the maximum value consumed by the burner, but the title of the chart does say that the "Yes/No" refers to "Full flame capabilities with no flame distortion".
Note 3: Chart might have been courtesy of Artistry in Glass.

BURNER | Alpha | Bravo | Lynx
LPM REQUIRED(LITERS PER MINUTE) | 12 | 31 | 7
EX 5 5 lpm @ 7 psi | No | No
EX 10 5 lpm @ 10 psi No | No
EX 15 8 lpm @ 15 psi | Yes? (66%) | Yes (2 units)
H1 15 lpm @ 20 psi | Yes | Yes (2 units)
REGALIA 10 lpm @ 7 psi | Yes (90%) | Yes (2 units)
OGSI 15 7 lpm @ 12 psi | Yes (60%) | Yes (2 units)
OGSI 20 10 lpm @ 15 psi | Yes | Yes (2 units)

I believe the problem you will have is matching the pressure output of the OG-20, but as I remember, that is not a big problem because the outlet pressure of the OG-15 and OG-20 are adjustable.

I don't believe the compressor is absolutely necessary for intermittent use. However, I am speaking about short, intermittent use using soft glass. It is an additional expense, so I think you could use a step-by-step approach and see what works for your situation.

For the time, expense, and effort for the holding tank (unless you know someone who is comfortable with the work), I think the best thing is to look for an additional, used oxygen concentrator (unless you take the rented oxygen cylinder route). If you are judging by the price of a new or used OGSI unit, the repurposed medical oxygen concentrators can be found for much less, especially if you are patient.

Also, I might add that if you have a local beadmaking club / ISGB chapter, you might find some help there. If you feel comfortable sharing your general location, someone may contact you.
