I forgot to mention that I saw a set of plans on ebay for around $10 to build your own bender. I don't know how good it was (I wasn't actually looking for plans for one, so I didn't spend the time to find out) but from the pictures it looked OK. For $10, you really can go wrong. If there crappy, sell them to that neighbor that you don't like for $15 (LOL).
