I own the Voyager and it's a great piece of kit, my only wish is that it was wireless, but the team has clear reasons why they've stuck with wired boards (https://www.zsa.io/wireless). A trackpad would be lovely. Very portable and comes with a great key editor to handle layers.

Also worth checking out the one-man Bastard Keyboards (diy and prebuilt), he does the Charybdis kits with trackballs, or the Dilemma Max split mech with a trackpad alongside ortholinear keys: https://bastardkb.com/product/dilemma-max-prebuilt-preorder/
