The product is worth what the Seller and the Buyer think it's worth. These eBay prices must add the Tax (~ +10%) and the Delivery to Europe.
MY ("MY", not yours, but MY, ok?) evaluation is that for this bundle in Europe, the price should be at least 5K. PERIOD. This is MY opinion and I know much better than you how eBay or any marketplace works.
The current price is SO LOW that was "Reserved" in just two weeks, this is RAPE!
A recommendation to anyone: Never ask others how much your stuff is worth, mainly here in this blog, they will depreciate your stuff a lot.
A while ago a "Super Contributor" told me that my Like-New Fluke 289 should cost $100 !!! Guess what? I said, "ok, go ahead and buy elsewhere, my price is firm", I easily sold it on eBay for 5.5x that value.
