My son has been taking Tae Kwon Do for almost 4 years now. One of the things a student must learn is how to break a wood board. This is sometimes the most challenging part of Martial Arts training.
To help my son become more confident at board breaking we brought him some rebreakable boards through Century Martial Arts.
What I like about these boards is they are made of a very sturdy plastic and can be used to break again and again. They come in 7 different colors, white being the easiest and black being the strongest. My son usually works with the orange, yellow, green or blue boards, depending what style of break he is working on.
These boards are good for any kind of break with the feet or hands.
These boards are a little pricey. They run about $80 per board, but they will last a long time and last many breaks. We brought our first one 3 years ago and it still looks like new.
Another good thing about these boards is there is a rubber grip on the underside, so whoever is the board holder has an easier time holding the board and keeping it still.
Working with these rebreakable boards has built up my son's confidence when it comes to breaking a board.
I would recommend these to any martial arts student.

Update On Apr 12, 2008: I just wanted to add how these actually work.
Like I said they are make out of a sturdy/hard plastic. There are interlocking grooves in the middle of the board. So they can be put back together by the interlocking grooves to be rebroke again.
