I thought they were illegal as well when I had mine., I hid mine everynight, and when I wasn't using it. (Though I didn't go to extreme measures to MAKE one, it was a GM mistake and accidental.) Until somebody stole it and was bragging about taking it. So I paged on them when I knew the player had it in his backpack, and a GM showed up *completely visable* at the WBB and told me it was legal to own, illegal to make.
Hope this clears it up.
