Get one that says 9 speed and has a barrel adjuster at the cable stop, some of them don’t.
The problem is that I have both read how the 9 speeds work fine on older 7-8 speeds, and I've also read how they don't on this forum. I've read how the Tourney is total junk and I've been told it is just fine and only needs adjusting. I did have it professionally adjusted after I tuned it as much as I could and it still will occasionally shift on me under very hard peddling and I have dropped the chain a couple times.
Actually I was only trying for a definitive answer.
