Of course the advantage of getting an oxygen concentrator goes to a new set up. One can most likely be bought for less (and probably much less) than a tank and regulator and flashback arrestor. Then there is the matter of greater safely and convenience.
A concentrator has its issues. It probably doesn't have the output for rosebuds and it takes a couple of minutes to purge the line until nearly pure oxygen is coming out. Also they make a racket if the line is cut off to warn Grandma she is about to die because her O2 isn't getting to her. This can be annoying if you turn off the knob by mistake.
