Should I buy an iPod Touch and the Shuffle?

I am saving up money from my job to by the new iPod touch (my other mP3's been broken for months!) I am stoked to buy the new iPod touch because it's got sick applications and is just plain awesome. However, I intend to exercise a lot. I'm afraid of dropping the iPod touch on a run or in the gym. Would it be wise to invest in a 1gb iPod Shuffle just for exercise purposes? Or should I stick with the iPod Touch? Thanks.
