A quick note about Rock Band:
You don't have to buy it at $170. That's merely the ultra-delux bundle. The actual game is the normal $50-$60 + the perpherials.
Like I've said in other posts: Guitar Hero is $170 for the game and just 2 guitars. No drums, no mics, just 2 guitars. You get a 3 player Rockband (ie, superior) experience for a 2 player Guitar Hero 3 price.
I plan to pick this up at some time. Definately don't want to dole out the cash, but I have alot of kids that are dying for this or Guitar Hero.
Back from the dead, I'm afraid.
