$24.99... WHY?! Radio Shack & Best Buy have the Dynex adapter for that price... Are these any better than the Phillips one for $10? I wanted to get the Phillips adapter at WalMart, but they've been out of stock forever (or at least when I go in to purchase one). I picked up the Dynex at Best Buy today because I'm sick of waiting. I'm hesitant to open it because of the price difference. Does anyone know why Dynex is $25 and Phillips is $10? Is it "better"? Better sound quality? More durable? Anyone?
