Also available in stores. I bought a couple yesterday.
You'll probably be able to buy other slightly more expensive boards online which offer better energy absorption, but this is more than enough to cover most surges one would get at home. I bought a board online a few months ago and was very disappointed at the quality, would much prefer something I could see and touch in front of me, so feel free to drop by the store to have a look first.
