Rip-Off

Touch wood, I've never been ripped off too badly. I can't think of a time when I've bought something, got it home, then realised I've been done. This is partly because I'm very tight and check everything on the internet to find the cheapest price, but that doesn't stop me from feeling sorry for customers (read 'victims') of Wants second hand shop in Exeter.
Since last year, I have been the proud owner of a second-hand guitar amp. It's loud and heavy and complicated and could be mistaken by the untrained eye for an expensive piece of equipment. It contains all sorts of digital cleverness and it's hard to find a part of the unit that isn't adorned by at least ten billion flashing red LEDs, making this amplifier the ultimate meat in a sandwich between a naiive, excitable, guitar-playing window-shopper and a devious, unprincipled second-hand electronics salesman. I'm glad to say the aforementioned customer was not me - by the time I went into Wants on the occasion in question, I had already bought this amp. I know this because I remember thinking ooh, that's my amp - I wonder how much they're selling it for?
My first fear, that I had been ripped off when I bought mine over eBay, was allayed immediately - I had paid a lot less than this, but surely this couldn't be right; they were selling this amp for £350! Oh, sorry, the exclamation mark doesn't mean anything to you yet because you don't know how much the amp is worth. Well, let me set the scene. The amp in the shop had two dials missing, which immediately triggered alarm bells because my one seemed pretty indestructible. Given the level of abuse the amp must have taken to lose two dials, you would certainly put the price for this one somewhere under the price of a brand new amp, but then you're not a devious, unprincipled second-hand electronics salesman, are you? If you are, I've heard there's a new fad called not being a dick - you should try it some time. Anyway, for your information, the price of my amp, brand new, would have been £190. The price of mine, a pristine, second-hand-but-never-gigged model, the only damage to which was the array of horrible nu-metal guitar tones with which the previous owner had dirtied the amp's memory bank, was...£110. So, just in case I haven't milked this enough, which I'm not sure I have, let's recap. A fundamentally identical amp to mine but in worse condition was on sale in Exeter for over three times what I paid for mine, and nearly double the price of a brand new one.
But this isn't the saddest part of the story. The saddest part of the story is that when I next went in the shop, the amp had gone. I'd love to believe that it was gone because Trading Standards had stopped by and taken the amp away, or that someone had walked into the shop one day and, having pointed out the obvious and honest mistake in pricing the amp, had bought it for the £90 it was worth. Thing is, I don't believe that. I think someone bought it for £350, and that makes me sad.
Actually, there are two even sadder aspects to the story. The first is that I didn't point out to the proprietor just what an arse he was being. The second is that, when I'm playing some mean blues with a creamy distortion and a touch of delay through my twin 50W speakers, I feel a bit smug.
