i know i didnt mean to offend but being 13 and i am not complaining and using my age but i get 25 quid a month of my mum and dad and that pays for the walk on so i cant buy expensive tanks.
ok you could probably get away with a steel bottle, which are much cheaper but its up to you, as 68cu is pretty heavy in steel tank terms, you'd be better off with a 48 cu. (£30 - £50 off these forums)
The amount of shots you get out of your tank depends on what gun you have. You will probley get around a few hoppers out of a 3000 psi one however, it really does depend on your gun and the upgrade.
You will be able to get a new one for about £50/£60 and a used one (depending on quality and how many years it has left before it needs to be sent off for a test) for about £30.
cheers for the help yeah i thought the 68 cu tank would be quite heavy so i will go with the 48 cu when i have money. i have a spyder victor III (you gotta start somwhere).
