We only have 2 teenagers in our church, graduated 2 in May so I cannot count on them. But your right about teenagers figuring stuff out way faster than most adults.
I belive mediashout was around $500 which is quite a bit for us.
I went with PowerWorship because I thought some of the less geeky people JUST might be able to figure it out easier than one of the other ones. But it does work for us and that is fine with me.
