For an HVAC system, how do I punch a hole in the sheet metal and install a take off?

I want to tap into my HVAC system to run some heating registers into a new room. What is the best (and cheap- this rules out that Greentree tool) way to punch a hole into the sheet metal of the square metal soffit and then install a take off?
