hhahaha -- here again - I think they are mostly porportionate to what they offer. Whether it be the quality of room and board or including travel to comps, you need to narrow down your criteria. They are all good. Finding one that is going to match your personality and reason for going to an academy is the hard part.
If you are just trying to shop price, you will not find one that is free unless you are a poor destitute top Junior Racer with contacts and race results. Sort of a catch 22.
If I were in your shoes, I would get to an academy that has people you know attending, learn the lifestyle and determine if you want to transfer, continue on or do a "been there, done that".
Browse websites and get on mailing lists. I have no idea of how we ended up on so many, but I bet we have recieved over 40 different invites to various schools and camps all over the world this spring.
