If one were to go to a flea market and snoop around the Asian-ran super cheap imported Chinese junk tables one would very likely encounter these units for $20.

Some Nintendo games are useful for developing shooting skills in the privacy of your own home. Uncle Sam thinks so too and at least used to use a Super Nintendo and an M-16-like lightgun to play a game to teach basic rifle marksmanship. Hogan's Alley is a good game for shoot/no shoot practice, especially since the good and bad targets are often similar to eachother. Wild Gunman can help build reflexes.

buy a real NES and a Zapper. It'll be better quality, and the trigger feel aint too bad ;)
