A new bundle due out in North America from October 25th should get you sorted. The so-called "New Owner's Kits" includes a new DualShock 3 controller (in black), a USB charger and HDMI cable for $69.99.
Seeing as a new controller costs $54, there are savings to be had. (Perhaps just about).
We'll be honest, it's not the most thrilling package in the world. But if you're new to the system it's probably worth picking up alongside all the exciting bits and bobs.
