In search of a demagnetizer

In our search to prolong motherboard life (this is our second replacement for the ISAAC 16), one problem we found was that our battlebot frame had become magnetized from the welding process, and we believed this might have an adverse effect on our motherboard performance. We began looking into how to demagnetize our bot and found that we needed a degausser. Some we found where here: http://kanetec.com/Demagnetizers.html we'll see what we end up with.
