I recommend a premod for your kids. You wont need to send it to a pro to get it modded. Well if you want the extra features like fast boot mode and being able to play media player thru mem card is good. Messiah2 is good mod for you if you dont want all of those features but want a good chip. Mars2 and Magic V for v9 is good. Well I hope this helps.
