Mechanical Keyboards

Many years ago I got the KBD75v2 and I love that keyboard, it's still my main keyboard for my home office. I now need another keyboard and was shocked to find that KBDFans doesn't sell it or anything like it anymore. I also cannot seem to find a keyboard that is 75% and has the possibility of split-space and QMK/VIA. Is there one available out there? Closest I can find is some Keychron Alice boards but I would like a non-split board and just have the space split into multiple keys. I've seen on some sites that the Wobkey Rainy 75 has an add-on for split-space but I cannot find that add-on anywhere and from youtube videos it doesn't seem to be included in the box(?). I'm also totally fine with soldering and piecing together parts. I just can't seem to find anywhere to start with that. I feel like the custom scene has reduced and the prebuilts have gotten better but with less customizations like split-space.
