What Would You Choose

I was thinking about Harry inheriting Sirius' property, and I got to thinking more... If you could buy, inherit, or otherwise acquire any magical item from Harry's world - anything at all - what would you choose? To whet the palate a bit, you can assume that the object would perform for you just as well as it did if it had a previous owner (so, if anyone calls dibs on, say, DD's wand, better not use it in close quarters!)

If I could pick, I'd like Crookshanks. He's not very magical on the surface, but he's an excellent judge of character and quite a bit smarter than my own sleepy cat. Ooh, it'd be really excellent to have my own Room of Requirement, too!!!

Other than a wand, a room of requirement would definitely be sweet! Very handy. Dead useful as Hagrid would say. I'm trying to think of something new though. Hmmmm, I'll have to do some more thinking.

I'd have those delicate silver instrument so I could figure out what they do!!

A Marauders Map! And a broomstick would be nice too.

Well a wand. And maybe a puffskin. They sound so cute.
