Wow, you people... Read into the situation a little. The fact that it's an "adjustable multi-button gaming mouse" is not the only thing - or even the main thing - that makes it expensive. They are more complex than the standard mouse, more advanced (duh), and generally use higher quality materials. This combined with the extra hours that went into designing it and the extra work required to make it (plus a bit of propaganda) is what raises the price to such high levels.
