Dude, I don't get your fear of buying from Amazon or Ebay. It's not nineties anymore. They have solid buyer protection , I can vouch for it, since I've used it few times , every single time successfully. Aliexpress and GMarket are a different story, I wouldn't buy anything over 50 bucks, since their Buyer protection policies are crap. Also, there are a few excellent online stores for HiFi audio that carry various portable gear, ie. Redfli, Penon Audio, JetAudio etc. Hope this will help you in making your decision.
