Hi, OrneryPest -- I'm one of your son's friends and went to Ryken and college with him.
Anyway, Ryken has its fair share of problems, but I chose to go there over Chopticon for various reasons. I liked its smaller class sizes and its spread-out, college-like campus. I think a good student can do well anywhere, though, depending on his/her social circle, classes, and after-school activities.
I also think more Ryken graduates end up going on to college (correct me if I'm wrong). The environment seems more academic, although you do get plenty of "bad apples" anywhere you go.
Choose what's best for you and your child. If cost is a problem, don't go to Ryken. I'm not sure the current price is worth it.
