Amazon has the Samsung dock for $26.27 and the Hyperion one for $24.99. The question is which one to buy? I need two of them, one for work and one for home, so I'm looking at a total cost of $60 to $70, and I want to make sure I get the best ones. I don't think I'd use the external charging feature of the Hyperion, so that's not a factor. Anybody have any experience with these?
