Aluminmum C02 tank

[bernie]

I require more information on Aluminmum C02 tank because I intend to get this over the steel ones because of the weight.

What is the price like and where to get? Will it be easily dented ?

for prices, do check with lfs.
a lot of lfs do carry them; nature aquarium, petmart, c328, ...

it will not be dented easily. the tank wall is quite thick actually.
