I saw that Weikav released an aluminum leaf spring Alice keyboard called Record, it is less than €100 barebone on aliexpress and probably even cheaper on taobao. Kind of crazy how many cheap aluminum keyboards that have come out lately
Weikav is the one that made Sugar65 which you can get barebone for €60 61.63€ 56% OFF|WEIKAV Sugar65 verdrahtete kunden spezifische mechanische Aluminium tastatur 66 keystype c Kabel dichtung struktur hotswap rgb hintergrund beleuchtete Gaming Tastatur| | - AliExpress
Both use their own software for customizing the keys. I would have ordered one if it supported QMK
