Potential for a rarity, but IDK:

I'd be interested to know if any Genny collectors have the Sega wireless 6 button pads (I'm starting to think I'm the only one! It seems like I'm always the sole-party bringing them up. ). So far, the ones I bought new (96-97) are the only set that I've seen, and they are awesome controllers. They are IR so if you aim it too far off from the receiver you will lose connection, but in my experience that is rarely a problem. The beam angles seem to be fairly wide. Many have stated before that the wired 6 button pads can be a bitch to track down (I'd have to agree, as I've been hunting a pair of 6 button sticks for years...), but I've never sought the wired pads, because I had the wireless pair for so long.

Also, the Sega wireless 6 button pads are not listed in the online rarity guide under search criteria: Genesis > non-cart items
