150$ is a baseline for a build that will be noticeably better than a gaming keyboard - Keychron V series (100$ for fully prebuilt, and then modding), Akko, etc.

Keychron is probably one of the best entries, as their Q/V series have VIA and QMK support (proper remapping, layers, etc.), are easily moddable and prebuilt versions offer great value, giving switches + PBT keycaps for 20-30$.
