are you intending to play tourney games in future, if so dont waste your time, you may as well save a little bit more and get a mechanical cocker or somethin along those lines, you can get em brand new on ebay from states for around £180.00 that way you dont have to buy new markers, you can simply upgrade the one you got ?
"but hey thats just my opinion i think spyders are a bit over priced for what ya get "
