I've always been interested in buying one, but since I'm curre tly budgeting for other major investments I'm not willing to spend like 350€+ for an ergodox. Are there decent sub 100€ non diy (i have never soldered anything in my life) split keyboards around afayk?
If your main concern about DIY keyboards is experience, most DIY split keyboards only require through-hole soldering, which is easily doable even with a cheap soldering iron.
Microsoft Sculpt is quite good. It is not mechanical, not truly split. But one that my hand can agree with. It is also the one I travel with because the mechanical split I have is too heavy.
I don't think you'll find anything non-DIY for under €350. The cheapest options are probably the Chinese/AliExpress ortholinear ones[1], but even those still cost more.
I recommend getting into keyboard groups on discord and facebook. In Australia I've seen people selling second hand assembled split boards for less than cost of the parts.
