I've got a 3rd gen nano and a new school bag with a more convenient media player pocket. I'd like to actually make use of it, but I don't want to be reaching into the pocket every other minute to change things. The only remote I could find on Apple.com was the radio remote, but I don't want to spend $44 on it when I'll never use the radio. Is there anything anyone can recommend that is relatively inexpensive and reliable?
