For the benefit of others, and to ensure my own sanity in reading it, here is a sub-editted version of Astrodev's post complete with sentences and paragraphs:
Editted quote from Astrodev:
I had a problem a couple of years ago when I was trying to get hold of a particular Maynuo micro power supply. None of the dealers who did Maynou offered it at a realistic price, if they could offer it at all. The two European sources never seemed to have them in stock, so it was back to ebay or Amazon. Ebay sellers were from China, were quite expensive, and you knew that you were likely to get hit with import duty and possible poor service in the event of a problem. So when some of these started popping up on Amazon from UK sources at a realistic price it was of interest until - this is where is sort of returns to the original thread here - it turned out that the sellers accounts had been hacked. A load of products from all sorts of categories had been uploaded. Anyway, thus began a cycle of ordering one and waiting to discover that, about 5 days later, the order would be cancelled without any explanation. This went on for several months as I just kept repeatedly ordering in case I hit a genuine sale; never did but must have had 40+ cancelled orders at the end of it. [What's that quote about the definition of insanity being repeating things and expecting a different result? ed]
Ended up getting a used Rohde and Schwarz unit that would do the same job.
