I bought the Wireless Network Adapter and the Quick Charge Kit.

Street Fighter IV TE Arcade Stick
Xbox 360 Wireless Controller
Nintendo DS

I got the core Xbox 360 in 2006. You get the Xbox and a wireless controller essentially. So obviously I need to beef things up.

I have bought:
-1 wireless black controller
-1 wireless red controller with play and charge
-20 gig hard drive
-Wireless mic
-Xbox Live Vision cam

I have put a lot of money into my Xbox and will probably soon be upgrading the hard drive. I still have my original Xbox Core from 2006, it has served me well.

I got a 256MB memory card just in case my hard-drive breaks I don't have to rush out and replace it.

Scene It came with 4 buzzer controllers.

Lips came with 2 wireless mics.

Got a black face plate at the dollar store (official surprisingly enough)

And I purchased a used wired controller.

Well controllers are overpriced. Microsofts HDDs are extremely overpriced and the 60 gb comes with no Transfer kit.

a wifi adapter

120 Gb HDD

Second controller

Play and charge kit + the official dual battery charger.

I don't use Wifi home (too slow..), so I didn't get the wifi adaptor...

Extra Wireless Controller
VGA Cable
120GB HDD
HD-DVD Drive
Play and charge kit
Quick Charge kit
Extra battery pack
GH3 LP Guitar
GH2 Xplorer Guitar
Rock Band Band In A Box (drums, mic and guitar)
ION Drumrocker kit
Scene It Buzzers

No I have lots of money to waste, yet I still wont buy a PS3. I have no reason to buy one.

I have all the accessories except play & charge kit (don't need, I got the energizer dock charger) and the wi-fi.

Most accessories, I got was bundle with something and on clearance. (camera kit was $10.00 with You are in the Movie at Best Buy, wireless headset bundle with End War, chat pad & head set bundle with Live 12months kit & PGR4).
