I've been looking at things like the xk3y and the Wasabi 360 (I'm sure there are others, or if not, there will be) but I don't know which is the best choice. Does anyone have enough knowledge about them that they could share the pros and cons of each one? Or maybe a link that compares them? I can't really find any decent info other than people on forums saying "this one is better!", "no, this one is better!" which is useless really.
