Need some tank help

Yup stay away from those China tanks!!!

What rifle are you getting? If it's a smaller air tube you might want to go with a hand pump until you figure out if its your cup of tea. 

But if your really set on buying a tank I would look into a used SCBA tank on Ebay. 

You can find some good deals with a few years left on them. And can pick up a fill rig for about $125 if you look around.
