I have a dual deck VCR which allows for one button touch copying of VHS tapes. It's perfectly legal. Memorex was taken to court for developing and selling it, and the ruling was that it was fine to make and sell such a product. Memorex also states in their manual that anything copied should be for personal use only.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
