Oxygen & Acetylene setup advice

The Victor and Miller kit at the welding shop has the flashback included. I’ve used a torch but, it’s been a long time. I’ll be sure to study up before using. The tanks alone cost $500-600 for the initial purchase. Both suppliers don’t bother with the small portable tanks. The total investment is roughly $1100. I’ve looked around for a used ones but, you don’t know what you’ll get. I’m going to have to think about it since that’s a lot to spend. Thanks for all the suggestions. Craig
That sounds like pure bullshit, what town is this? When I worked in HVAC, we all used the little "suitcase" tanks because you had to drag them all over the place, into basements, up ladders onto roofs..........

So far as LP for cutting just do some googleing.
