## Price and value observations

Across these 8 products we hold 8 dated USD price observations, the earliest from 2026-08-26 and the most recent from 2026-08-26.

Every product here carries a single observation, so what you see is a snapshot rather than a trend. We do not draw a price history we have not collected, and we will not tell you something is "on sale" on the strength of one data point.

## Availability

Of the 8 products here: 1 discontinued, 5 in stock, 2 out of stock.

Out-of-stock and discontinued products stay in the ranking; we do not silently drop them, and the price shown for them is the last one we recorded, not a live quote.

## Who this is not for

Who this is not for: skip this page if you can comfortably spend more than $150.00; or if you are not shopping the 75% end of the catalogue. We have not physically tested any of these — every ranking here comes from manufacturer-published specifications and prices we tracked ourselves, so if you want hands-on impressions this is the wrong page.

How this page was made: the question is hand-written, and everything below it — the ranking, the comparisons, the price and stock observations — is computed by deterministic code from the same corpus our product pages render from. No model writes the analysis, and no editor re-orders the result.
