That's the correct one. A word of warning, the magic rack is the original but it has issues. The material is thick enough that it will cause roll offs if you don't take it off after the break. It is also thick enough that the balls are not simply frozen, but "pre-loaded" against each other. This will make them explosively break, more so than a perfectly frozen rack with a normal triangle. You can break way softer with a magic rack for this reason. They are fine and a good rack, but the ball action is not realistic.
The outsville is thin enough to not cause roll offs or "pre-load." It acts like a perfectly frozen rack like you would get from a triangle. You do have to learn to use it correctly, it takes a small amount of user skill so it's not as "drop the balls in" as the magic rack is.
There are other racks. Forget the cheap thin knock offs, they are total shit. You can get like 10 of them for $12 but they are super thin and poor quality and will not rack as well, and also wear out faster. I have original magic racks from somewhere around the early 2000s. It's still perfectly usable.
Turtle racks are good, but somewhat thick so some of the same problems may apply. The thicker the racking material, the more tendency to cause roll offs and the "pre-load" issue. The "pre-load" isn't a horrible thing, but just realize it breaks way easier and way more explosively than a normally racked rack. If you're in a tournament and playing rack your own with a triangle don't expect the same break as you get on a magic rack, even when perfectly frozen. This is why I like the outsville as it's the most similar to a perfectly frozen triangle rack.
