Cheap airbrush: Airbrush Equipment Board

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

2 of the 21 named sources that could be read published a usable figure; 19 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 61 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per model: needle and nozzle in millimetres, feed (gravity, side, siphon), action (single, dual), cup volume, the maker's own stated working pressure, and for compressors the tank litres and duty, for resin printers the screen resolution, build volume and stated speed - each beside the maker's own price where one is published; the board's figures are the price per model class, the count of models at each needle size, the cheapest model that publishes a 0.2mm needle, and what the maker's own spec says against the kit price a retailer shows

61 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
