Why this number?
The typical used price is the median of 9 used sales observed in the last 6 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 | €200 | median sold, rounded |
| Most sold between | €200–€220 | 25th to 75th percentile, same window |
| Window | last 6 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 | €200 | 15 used sales, 2025–2026; not used for deals |
| Sales on record | 17 | 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

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.

Price history
Every recorded sale, one point each: 17 of them, placed by the day the ad went up. Too few sales to draw a trend through them without inventing one, so the points speak for themselves. Condition is mixed, so some of the spread is a mint against a fair rather than the market moving.
