if youre asking "should i buy a spyder or an old cocker"
then i would advise you to buy a cocker, and so would most people with any sense !
the reason for this being that you can upgrade a cocker to your hearts content and it will still perform brilliantly without the upgrades.
old cockers will also quite happily run on co2.
my spyder sport and e99 both chopped paint like hell.
my cocker doesnt seem to do that. could be because it has an anti chop eye but there you go, just proves my point about upgrades. there isnt many features that you cant get for a cocker that are on other paintball markers that are useful.
A cocker with an electro frame can shoot 22bps with the eye turned on. i would be surprised if any spyder could even come halfway near that considering mine chopped at fully auto at 13 bps.
my 2cents.
