We had this one, years ago. It lasted a long time but did eventually get replaced. But it didn't cost that much when we bought it! Also look at the other ones suggested for people looking at this one. Vesper brand is one I'm familiar with that has a nicer aesthetic.
Costco often carries sturdy ones with neutral colors. Still ugly in shape but less ugly.
You can also find some nicer wall pieces and do more of an installation. It's bigger and more work, and money if they are attractive, but it can be intentional in style vs trying to jam something in a space it doesn't fit in.
Ime, cats want to be on the edge of the action. So a room others use, but a less frequented corner. So I wouldn't try to hide it in an unused room.
Having one allowed scratching surface per room will help, btw. When kitty is older and more chill you can cut back.
