I like sporting clays, skeet, and trap, in that order. To me trap seems to be more of a one-trick-pony. Sporting clays, and to a lesser extent skeet, makes me a better field shooter by allowing me to practice more realistic shots. To those of you who have built your own skeet range, did you do it yourself? What range of cost can someone expect for the houses and throwers? Does the equipment require lots of upkeep?
