Explore Scientific, on its own published figures
Explore Scientific sells under its own name and under National Geographic, and its cheapest printed telescope is a 114mm reflector at a sale price of $91.00 against a regular price of $149.99. That is the largest aperture per dollar in this index by a wide margin, and it is a sale price, which is exactly the kind of figure that moves.

A sale price is still a printed price, with a date on it
This index quotes what the page printed on the day it was read, so a sale price goes in as a sale price rather than being smoothed into something more durable. The regular price of $149.99 is printed beside it and is quoted in the same cell, so a reader can see both and judge which one they are likely to pay.
The page states the aperture in its standout features and states no focal length anywhere, so the aperture is published and the focal length is recorded as not published. For a 114mm reflector the focal length matters, because it decides whether the instrument is a wide-field sweeper or a planetary one.
