Mid-Tier UE5 Camera tracking hardware?

I’m looking for a commercial mid-tier UE5 compatible live camera tracking hardware solution for a virtual studio, preferably with good manufacturer support based in EMEA. 8x8x4m green box, 3x URSA Broadcast, needs to be stable enough for extended (2+hrs) live production in a commercial environment. Optitrack is way over budget, HTC Vive Mars (other extreme of the budget scale, it doesn’t have to be that cheap) is too cumbersome and unreliable. Antilatency looks good on paper, but it’s really hard to put a price on a working package with their products, they don’t have a proper EMEA sales office outside of Cyprus and their sales response is lackluster at best unless you want to sign up for a support subscription right away… So what else is there?
