When looking for supplies I needed  the whole set up but ended up piecing it together and was a headache. I purchased the Smith 30 regulators and oxygen tank from Paxair and purchased the a cheap clone look alike of the Smith torch online and within two weeks it was fried! So I purchased the real McCoy Smith torch and had been a dependable friend. Reason why I am selling these units is my new style of jewelry making doesn't require soldering and is all done with hand tools and metal roller, my opals are pre-cut and shaped and all I have to do is build the frame. The regulators are covering my name and address on Smith box to show you it is a Smith torch.
I had used the unit about 35 times and the equipment looks like it is brand new, when using the equipment all those times my gas/oxygen gauge % never even moved. There is no oxygen in tank and will cost less than $10 to fill. I used a propane tank from my BBQ grill for initial gas, by the way it is not included. I think even if you use the your equipment a lot the oxygen tank will last a year. 
The pressure setting I was using was 7 psi for gas and 5 psi for oxygen, this unit will melt sterling silver in a blink and I believe it will melt gold in a small ceramic cup. The unit was a joy to work with.
When looking at box size to ship, a larger box would have cost $60 anywhere in USA, So I am placing it into a smaller box and cut half the price for shipping but I assure you it will be packed very good and protected. By the way when viewing the regulators it looks like the glass is scratched, it is not.  Just dirt on it and I will clean it up before shipping.        Enjoy
