{"knowledgeAsOf":"Early 2025 (approximate; prices and availability may have changed since)","picks":[{"rank":1,"product":"Keychron Q1 Max","manufacturer":"Keychron","reason":"Gasket-mounted aluminum 75% board with wireless, hot-swappable switches, and QMK/VIA support, a very strong all-rounder.","caveats":"Typically priced around $190-$220 and may exceed $150, so it does not meet the constraint. Not recommended if the limit is strict; see the rank 2 and 3 picks."},{"rank":2,"product":"Keychron V1 (or V3/V5 depending on layout)","manufacturer":"Keychron","reason":"Hot-swappable, QMK/VIA-programmable, and solid-feeling for roughly $85-$110.","caveats":"Prices vary by switch and layout, and the exact variant sold may change. I am fairly but not fully sure of current pricing."},{"rank":3,"product":"Wooting 60HE","manufacturer":"Wooting","reason":"Top-tier Hall-effect analog keyboard with adjustable actuation, loved by gamers.","caveats":"Usually about $175, over the $150 limit, and sometimes sold out. Under $150, the closest honest alternative is the Keychron V-series or the Keychron K8 Pro (about $100-$110)."}]}
