Why this number?
The typical used price is the median of 9 used sales observed in the last 24 months, with outliers removed and the figure rounded. An observed sale is often the last asking price rather than a confirmed hammer price.
| Typical used price | €400 | median sold, rounded |
| Most sold between | €400–€420 | 25th to 75th percentile, same window |
| Window | last 24 months | the tightest of 90 days, 6 months and 24 months with 8 used sales |
| Sample | 9 used sales | thin data, treat as a rough guide |
| Time to sell | — | only counted from listings we watch start to finish; not enough yet |
| Outliers | dropped | beyond 10× the product’s own median: bundles, parts, typos |
| All-time | €390 | 67 used sales, 2015–2026; not used for deals |
| Sales on record | 68 | all-time, all platforms |
Typical prices are rounded (to 5 / 10 / 50 / 100 by size, in whichever currency you read); asks and the chart are exact. As of 17 October 2026. Full method, including what each badge means
For sale right now
The best-priced as cards, a row of them; every other ad as a line, by ask. Each ask is the seller’s own number; the platform’s mark opens the listing. Each one says when we last confirmed it at its source: the price and availability are from that visit, so check the marketplace before you go.
Nothing live right now on the platforms we track.
Price history
Every recorded sale, one point each: 68 of them, placed by the day the ad went up. The line follows the middle of the sales around each point, with the middle half behind it, and breaks wherever nothing sold nearby. Condition is mixed, so some of the spread is a mint against a fair rather than the market moving.
