Wow, that is so sweet of you! I tried to dig the net for you and I saw 3 great ones at MacMall. http://www.macmall.com/n/Bluetooth-Headset/macSubMenu-188
I prefer MacMall over other stores because I had a great experience with them when I purchased my own Bluetooth headset in one of their retail stores. Not being a techie, I needed some help to understand how things work. Very warm people, very accommodating. And the better deal? They're a SuperStore. Their shelves are very updated with the latest gadgets and accessories in town at good prices.
It's become a habit to check them out once in a while.
