What's your budget? I have also been looking out for something similar, mostly on r/mechmarket (I have an ergo travel that I am trying to get to work consistently).
There are sometimes deals like this: (not sure if this one is still available) at $80 https://www.reddit.com/r/mechmarket/comments/162uc4s/uscah_dilemma_v1_choc_pink_w_paypal/
Another place I've found really good prices is the bastardkb discord, but like r/mechmarket the postings for split keyboards are infrequent.
If you have switches and keycaps from a donor mech kb, this could be a good option at $128: https://www.reddit.com/r/mechmarket/comments/162uc4s/uscah_dilemma_v1_choc_pink_w_paypal/
Edit for completeness: $120 one piece option just without keys/keycaps: https://ergohaven.xyz/shop/tproduct/339856256-880659810681-planeta
