My choices are the EdGun R3M, Cricket compact or Hatsan Bully. I know I would have to do a little work on the Hatsan but it's probably the most powerful of the three. The R3M and Cricket are the most efficient and I figure accuracy is so close that it doesn't matter. Laugh if you want to hear me say Hatsans are as accurate as the higher-end guns, but I can attest that it's true.
