I hate to disagree (with Joe's criticism of Amazon) because it makes me sound grouchy. So far my experiences with Amazon have been great. I usually stick to items with free shipping, and returns have not been so difficult. They even fixed an ordering error I had made once when ordering tax software, and accidentally ordered the PC version when I needed the Mac version. I find their customer service easily accessible, and friendly to deal with.
I would love to buy at a brick-and-mortar store, but here on Long Island, no one sells Shortwave or Amateur Radio gear, with the exception of Radio Shack, and the Hamfests, which I will wait for if there is one coming. Even at a Hamfest though, the chances of finding something like a Grundig G-4000 is pretty slim. Radio Shack does carry some nice radios, but customer service at Radio Shack is a roll of the dice, depending on the quality of the manager, and his staff. Some are better than others.
I will agree that the overall quality of these radios peaked around 2008 or so, and seems to be in steady decline now. My Redsun RP-2000 is a horrible radio, constantly requiring jiggling of the controls or a reset to work properly, and my Tecsun PL-390 has a strange issue where if I don't use it at least weekly, the controls tend to "freak-out" when I go to use it next and have to spend 5 minutes working the dials and pressing buttons to alleviate the problem. I see the same thing in the Chinese Amateur Radio gear too. Although some of the radios are made to last, many are not.
