Well we are currently giving away jynxbox's sticks. This DOESN'T MEAM they are the best, but they are on par with any of their competitors.
The issue is that XBMC is still limited on any android device! BUT, can be made to work with the help of users builds, our the build done by our sister site XBMCANDROID.com.
The question, at this stage, is what is your budget. Tell me the dollar amount you want to spend.... We will give you options!
P.S. I love that you are getting something for your brother. As of this Christmas, I gave all 7 people on ,y family the means to enjoy XBMC! Aside from a lot of tech support calls, it was a GREAT decission!
