Rather than throwing them away, I re-fill and re-use my 1 pound tanks. I bought an adapter that fits on a 20 pound tank. I screw it securely onto the big tank and then turn the tank upside down and screw a small tank onto the other end of the adapter. Then, I open the valve on the big tank and it fills the little tank. It only takes about 30 seconds to fill. Then I close the valve and remove the small tank and cap securely with a brass cap until ready to use. Then I screw on another 1 pound tank, open the valve and repeat the process until they're all filled. This saves a lot of money and isn't too challenging. I usually do about 12 at a time and have never had a problem. They don't get 100% full, but they get pretty close.
I bought brass caps for the 1 pound tanks just so I can make sure that they can't leak if there are any problems with the internal valves. It's not a necessity, but I feel it adds a measure of safety .
If you do this the absolute most importnt thing to remember is DO IT OUTSIDE with plenty of ventillation and no ignition sources nearby.
