    The imported ones are not expensive, about $160 AUD, say about $100 US. The copper pipe needs to be annealed to prevent splitting.

    Yep, heat it up glowing and dip it into water. And you have soft copper. Copper tubing is work hardened when it is drawn over a mandrel.

    That particular model is about $500...

    There is a hand tool version:

    one place online has them for sale for under $50, but the reviews are not so favorable...

    This is the type I purchased, simple to use and works extremely well. And is inexpensive.
