You have to be willing to take a drive for a good deal, but what I have seen what you are looking at, it would be best for him to go and check it out.
Just a few questions:
1. How much does he have to spend
2. Does he have anything now to work with or is it a startup system
3. What type of music will he be playing, ie, what will he need to play, a CD player, MP3, TT?
I am sure if you put to gather some more information, a few of us can keep our eyes open and point out things that look good.
