OMG - four weeks til christmas???!!!!! I better do shome chrissy shopping!!!! EEEkKkk

I think DH is going to get clothes for chrissy. The kids pressies are all done. And I have my parents pressies, and one of my sisters. Now I need to get DH's, two of my other sisters (prob jewllery) and come up with an idea for my bro.

Does anyone have any suggestions as to what to get my bro? He is 25yrs old, is coming home for chrissy (lives in London) and then is taking off on boxing day to live in Canada for 6 mths. I love my bro, but don't know him well enough to know what he would like or needs. DVD's are out because he's equipment uses different formating. He has an ipod and doesn't listen to CD's. And it cann't be big or bulky because he is travelling...
And I have a budget of around $30 (give or take $5).

please help me come up with some ideas for my bro.
