Thanks to a tip, I was pointed out to these NEW weird looking grips. Appears to have infrared built into the grip, for what? This unit does come with a remote for just $29.95 + Free Shipping (no batteries), my only guess is that the Remote is using that Infrared area on the grip. If that were the case, they should have just designed the infrared to the 'Rear' of the grip allowing users to shoot from front or back with a standard infrared remote. Thanks for 'NOT' thinking that one through people.
You can find these grips starting as low as $29.95 + Remote + Free shipping, or at $49.95 + Remote + 4 Batteries + Free shipping. I'll try to find more information on these, because they do sound too good to be true at those prices, but the seller has incredible feedback on eBay, so all can't be bad.
