My thought is to hunt up your oxycon(s) first and see what you can get.

If you get a torch and don't have the oxycons to feed it well you will feel frustrated at being -this close- to getting what you want out of it.

But if you get the oxycon(s) first then you can get the most torch that your oxycons can feed without over spending on your torch.

Happy hunting.

Oh and you could hunt up a "homefil" system and some of the small used medical tanks. It wouldn't give you the purity of the commercial oxy tanks or the volume but you could do some "carefully planned raging of the torch" for a while by dumping some tanked oxy con into the torch when you want.
