Does the Slam Dunk manga wrap itself up properly or does it end abruptly?

I'm nearing the end of the TV series and it feels like i'm only at what should be the halfway point, but I see that the manga ended serialization around the same time the anime finished airing and there's only about 8 or 9 volumes ahead of where I currently am.

So is Slam Dunk just cut short or does it end in a satisfying way? I want to buy the remaining volumes but really don't know if that's a good idea.
