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
