This site sells Chinese products at good prices. The description of the items they sell sometimes omit key details, so you should do some research before committing to buy. If you can't wait at least 3 weeks (sometimes it can be two months), you must choose the express shipping. If something goes wrong, well, you're going to need a lot of patience; if is a cheap product, I advise you to swallow the bitter pill and consider it a loss; if is an expensive one, be prepared to pass through a long, painful ordeal. Customer support is BAD, as bad as you should expect from a communist bureaucracy: worst than this only at the airport in Havana, Cuba (I haven't been in North Korea, though).
