OK so here goes. i have been using one of these type rigs for my soldering and brazing! It sells now around $65.00, although I think I paid less for mine!! http://www.acehardware.com/product/..._clickid=5e250aed-bd4c-42ca-a961-1133b703349e The problem with this rig is the Oxygen valve is so sucky that you must turn it about six or eight turns to get it too come out and then even at best there is maybe 3-4 uses and the oxygen is used up. So you have to buy another oxygen bottle at the same cost as one MAPP gas bottle! Is there something better out there??? I have been thinking of one of these rigs. http://www.ebay.com/itm/Professiona...ing-Cutting-Weld-Torch-Tank-Kit-/361492160578 Are these rigs any good??? After reading the small print at the bottom of the page, I have doubts that these tanks are refillable!! I have seen these from this price at just under $200.00 and up!!!! So anyone got any advice on the subject of a soldering/brazing rig????
