I'm reviving this thread to let you guys know about an even better deal on the Band Hero kit for 360/PS3. London Drugs is selling the bundle for both consoles for $49.99 if you can find stock. Not sure if they have it for Wii, because I didn't see any. There was still some stock at my local London Drugs so I went to Future Shop and did a PM... Got the Band Hero bundle for 360 for $37.99 + tax!
Normally I wouldn't have considered it, because I already had a set of GH:WT plastic instruments, but my drum kit died and this was the perfect replacement... Plus I wanted to update before Rock Band 3 comes out...
