To be totally honest, NPC Mario Power Tennis is horribly broken. The controls don't work half the time. Sad because I wanted a decent tennis game with Mario. Though Grand Slam Tennis is good fun with MotionPlus.
Anyway, I wouldn't recommend NPC Mario Power Tennis.
I couldn't find any good deals on Amazon for any of the games. Some are still at the fifty dollar price tag new-- or more!
If you can find a copy at blockbuster I think Mario Sluggers was selling for $9.99 as far as condition goes that's entirely up to you if you find it and want to keep it.

I tried the nearest blockbuster and they didn't have much of anything. Thanks though
