Mechanical Keyboards

Hi, I hope it's okay to ask for recommendations on this sub, if not please just delete my post, or lock it down.

So back to the topic, I came here to ask if anyone could recommend me keyboard. I'm a software dev working 100% from home, therefore the keyboard I'm looking for is mainly used for work related stuff. Outside of work I'll also mainly do browsing, some office stuff and a bit of leisure coding. Gaming is (sadly) nothing I'm doing anymore beside maybe the single day once a year were I'm playing a few hours of factorio or something alike.

Currently I'm mainly using a Logitech MX Keys since my girlfriend got stressed by the sound of my beloved Corsair K70 with blue clicky switches. Since she's not working from home anymore I'm able to go back to a mechanical keyboard. I would like to switch to one of those fancy split keyboard things since their ergonomics actually seems to be way better then the one of a classical keyboard. I'd also like it to be wireless since I reorganized my desk and actually managed to get a nice cable free desk. Thing is, when I was looking around I found some wireless ergonomic keyboards but most of them were no real split keyboards and almost all of them had rubber domes and no mechanical switches. The mechanical ones I found were all cabled bound and for some reason also incredibly expansive. E.g. I'd really liked the Moonlander thing but it's already at close to 400 euros, I also liked the ultimate hacking keyboard even more, since one is able to attach a small trackball to it but it's also cable bound and incl. vat and shipping to Germany it's above 600 euros...

So to sum it up, I'd be really thankful if anyone of you has some suggestion for a nice mechanical wireless split keyboard.

Thanks
