how much do you think u'll be playing paintball each month? if you have a proper team that wants to train hard i find that the highend electro markers are what everyone uses as you can use them on woods and air fields.
If your going to only be playing on like walkons i wouldn't spend more then around £250 on a gun, get a good bottle and a hopper with a lid aswell if your not going to be doing this once in awhile as the speedfeed sucks in rainy conditions and if you don't play that regularly then theres nothign wrong with a good old lid
battle packs and about 6 pots shuold be plenty for now until you get into tourney's where you need lots of pods (or a pod bitch)
Got a upgraded shocker nxt f/s if you wanna buy it off me aswell ;D
