I was about to start a new thread on this, but did a search first, and found this thread.
Although I completely understand the idea that filling the 1lb bottles could be potentially dangerous, I have a question of those that make the comment about how cheap they are - just toss and buy new ones. Can you just toss them? In my town, we aren't allowed. Well, we are allowed, but it requires a $10 fee for each and every 1lb bottle you turn in at the town dump. $10 PER BOTTLE. So that cheap bottle of propane, isn't quite so cheap anymore.
I was looking at this article....

Any thoughts?
