pro's... unlimited portable air (tried taking a 12 ltr, even to the car )... con's... it takes a fair ammount of effort to pump up a gun... pro's a 3ltr 300 bar will be light enough to take anywhere... con's... you will get to know the guy at the dive shop really well

it depends on what you want... some say a pump (and this may well be true) cannot supply the moiusture free air a bottle doe's... but if it is fitted with a filter... its a close second.

have used both without a problem d/bottle for fill up's and pump as back-up for low bottle...

some would never use pump's... some swear by em... tricky box of frog's really

me... 12ltr, 3 ltr, lazy git... would recommend a good pump/filtered until you get a d/bottle.

hope this kinda helps
