Ehhhh. By the time you buy new hoses and the flash preventers, you're not saving much money over what you'd get in a brand new kit. I recognize the Victor regulator, but it's only a single stage and looks to be pretty old. I do not recognize the mfr of the handles...make sure you can get tips for that handle, if you can't, you're "hosed". The "Radnor" and "Concor" regulators....these are import brands which would work fine for you, but forgive me, this looks like a junkbox pile of old stuff.
I strongly believe you would be better off buying a used rig in good condition from someone who also has the tanks and getting something in better shape, and maybe you get a cart to move them around in or otherwise assist in keeping them upright which is VERY important. Know that you're still going to have to buy the gas botttles, yes? Those are either ownership items or rentals...but my point is 1: There is utterly no shortage of this stuff used, and plenty of it is in MUCH better condition. 2: This gear does not appear to be in good condition except for the new swap-in import regulators. This is a clue...he swapped in newer regs...the old ones must be shot....so in what condition are the torch handles? 3: What is there looks really, really used. There may be safety issues with how much that stuff has been used. Where are the hoses? You can tell a lot about the general condition of the rig by looking at the condition of the hoses. 4: You are better off buying a "whole kit" with ALL the pieces (you are still going to have to buy propane tips, no doubt, but those are cheap) instead of all the individual doodads piece by piece...and under those circumstances, maybe you get a better deal, on better-shape gear, with tanks (big expense) and cart, and you don't have to go buy "fill in" pieces at new retail which kills whatever deal you think ar getting a la carte on the bits and pieces. And you avoid the issue of mishmosh of brands, have to go here for a reg repair, have to go there for a new tip.
I would avoid that pile
