i agree with many of what u said, but i dont think it indicates that ur in a bad dojang, when u have to pay fees, a dobok and for belt tests. i'd rather call this ordinary. i depends on how much u pay and how much a get for ur money. an overpriced dobok, way too expensive belt tests and contracts, that can only be signed for a 1 to 3 period or something would indicate such "money mill" in my opinion. can be wrong though - maybe i didnt encounter too many different dojangs to judge.
