it depend upon what type of paintball you want to play and how much money you have or want to spend. if you are playing rec then upgrade a little, though the 4.0 is ok for rec. if you want to play tourney then a new marker is probably better if you can afford it. cockers, shockers, angels, RT mags, imps, sov2 are all available, starting costs are about 400 for a basic set up on the cockers, rt and sov2. and they go all the way to several thousend for an aurora eclipse shocker or cosker.
