Hi!
It's happening everywhere. Electronics have become more expensive.
Not only the final price for the item, which is often racked up to rediculous levels by greedy sellers, there's shipping costs, the cost of repairing gear smashed by careless couriers like Hermes, (who could smash a solid gold ingot!), obtaining manuals from non-free sources, custom/obsolete i.c.'s and other semiconductors, having to design adaptions for long obsolete or custom front–panel controls (I recently priced up a little DPDT switch with an LED–tipped toggle for a Japanese Oscilloscope and it was THIRTY–SIX POUNDS!)) – all factors you have to take into account even with perfectly honestly described T & M!
Apart from the above, another thread on this Forum mentioned the Israeli seller asking "sky–high prices for things that looked like they'd been run over by a tank!" – I came across a lot of those and I wouldn't touch them!
As for selling things claimed "untested" when vital boards, etc., have been filched from them, is pure and simple fraud, which the SNAD system is supposed to assist a buyer, but I did once write a guide on buying such types of equipment, unfortunately it only got a few views and eBay deleted it!
