Im looking into getting a new gun and dont want to spend crazy amounts of money beacause I am a nubbin

. Anyway the smart parts ion and the spyder rs seem to be some good picks that are around my price range ($100-$240) please keep in mind I will be running off of CO2 because of availability in my area. Please tell me your favorite and why as well as any other guns in my price range that run off Co2.
Thanks and sorry if this a repeat.
