I recently took up the hobby after a ten year hiatus (life happens).  I pay over $150/yr to belong to a local rifle range.  I pay $75/yr in RC club dues.  I pay hundreds of dollars per year so my kids can compete in softball and baseball.  The $58/yr I pay to the AMA is one of the biggest bargains in my life.  The magazine subscription alone is worth the pricethey pack a lot of information in each issue.
