they have some older reg that need a adapter to fit modern acc or propane bottles. i have a old victor that has a female threads instead of common male, for fuel gas that is. i think there is another variation as well but if it's seen little use i'm sure it will fit. i would look around for used bottles. also depending on what you will be using it for, mabey check into propane instead of acc. if you will be doing a lot of cutting it will save some serious $$. also i would consider the long hoses, you will thank me for this if you use it a lot. i have one small rid for my truck and you will always need to go 2' further than you have hose. i have two in the garage, one pro and one acc, and i even need the long hoses there. like for plumbing in the house or chopping cars in the back yard.
