if u wanna stick to spyders, and just upgrade it there are many things u can do to make it a great gun. If ur gonna play speedball then lose the tippman, sell it, get anything u can get within reason. Second, get an hpa tank, with ur funding 45/3000. Third, u need an elctro trigger, there are many u can buy. If u think ur gonna have like $350 then go with the Dragun "the One" Kit, ur gun will be great with that, but if ur funding is a little more limeted piranaha has a trigger that will fit spyders thats faster then any kingman trigger
