Which should I buy: Rockband 2 bundle or a BEATLES rockband bundle?

My husband’s b-day is next month and he’s wanted drums since he was a child. We have a Wii. I was thinking about getting a Rockband 2 bundle, a drum throne, some nylon coated drum sticks, and the cymbal expansion kit.

If you have this set, or have played it, is there anything else I’m missing/need to make his playing more fun?

I was thinking I could wait to get the silencers to see if they are actually necessary.

I’ve looked at all the options. I’m just not sure which to select or what else I might be missing to purchase.
