My guild made our first endeavors into Karazhan tonight (we're very casual about raiding, so we were late off the gun). Completely wrecked Attunment the Huntsman on our first try and got Moroes down to 16% after only three wipes. Unfortunately, we were cock blocked by the respawns (for some reason the trash mobs in Kara respawn as fast as a normal instance) and one of our main tanks got kicked out of his internet cafe. But we know we can take him down and are on the verge of being two bosses in.
If you check my armor page, I got my Harbinger Bands (lawl misspelled) off of Attunment. They were technically not upgrades, but I went zomzg epics and suicided for them (we use SuicideKings). It turns out I probably made a really good investment, because Blizzard is going to be buffing a lot of the Karazhan drops and my bracers are most likely going to be buffed to uberness.
Karazhan is really fun. It would have been better if the trash hadn't respawned, but I love the instance. Its also fairly ezmode.

There's funny.
And then there's asshole.
You earned it.
