I've seen Amstard GX4000 consoles go for 15£, I know that they usually sell for 40-45£, but a boxed one with a BuyNow price of 25£ (31 euros) is a rare bargain indeed. More so when both the console and box are practically unused, boxed, in mint condition and in their complete glory. So, uhm, here's the link to a boxed Amstrad GX4000 console. Seller ships within the E.U. only. Oh, and a previous Retro Treasures post on the thing should be quite enlightening too.
