i was in the same boat you were in.  I tested a a5 , i didnt like it at all.  My Boss won the national paintball tourney 10 years ago and he uses an Indian Creek, and his son uses a bonebreak.  When i went to play with them they tore it up.  Anyway they told me eletrics are the way to go.  Other then that auto-cockers are good. Psycho Balistic Diablo is a good entry level gun, but if you wanna pay 100 more and be a instant stand out get a Smart parts Ion.  $295 and your set with a bad ass gun that can compete with anyone.  Your gonna want an air system the tanks run from $69-200's ,  Its not a cheap sport at all .  Another gun i was thinking about getting was a WPG trigoly Pro, went to a paintball gun store and checked it out its cheap and looks and feels bad ass.  People will be scared of you once you whip that puppy out.
