The DSi/DS Lite starter pack comes with 2 replacement stylus, Dual Console Screen Protector Kit, 2 games cases and wrist strap. Bought from game station for £6.99 a few months ago (see picture)
The guitar hero mic is the official mic that comes with guitar hero. Works really well. I just use my singstar mic's instead.
