I've always had Victor regulators, hoses, handle & tips.
The kit came with everything but the tanks.

And that should be looked into prior to getting the other stuff.

Tanks can be rented or purchased. I bought small tanks and a cart. I can easily load them in the trunk of my Accord.

A couple of things to remember, tanks have to be pressure checked every 5 years, or you can't get them filled. Some places don't FILL tanks, they trade them. Lost a pair of custom painted ones that way once.
But trading is easier than filling, and most tanks are rentals anyway. Rental is probably the way to go if you want big tanks for little initial outlay.

And I must add that I'm very glad to have an oxy/acetylene set-up, every time I use it!
Which may not be often, but it's just the right tool for the job.
