AMA is $58.00/year. http://www.modelaircraft.org/

Club dues vary greatly with area and type of facility the club has. Don't just join the first club you go to. Check around and spend some time watching the members fly first to make sure they the kind of people you would want to spend time with. Also make sure the club is not dominated by one type of flying eg. 3D, Pattern, etc. unless that is the kind of flying that you want to pursue. Sometimes a new flyer has a bad experience from joining a club that he later finds out is not on his "wave length" so to speak.

Good luck and I hope you find a home real soon.
