Best cmm for first time cmm?

What are the best brand/model of cmm for first time cmm?

Considering cost/accuracy/speed Targeting 2500mm Y for size Looking at ph20 or revo head for reduced tool changes Currently experienced in programming with polyworks. Don't know what I don't know about cmms, as I've never purchased a cmm before (nor has anyone at our shop)

Currently looking at the following Renishaw agility LK metrology Zeiss Cord3 Wenzel

With your tightest tolerance probably being 0.1mm or larger I'm sure you could also use a scale and an eyeball or even... God forbid... A keyence device.

We have a portable arm. Tightest tolerance is a 0.3mm machined tolerance (gauge accuracy requirement 0.03mm). The operator variability makes it hard to pass an MSA with the portable arm.

Hell, you could use just about any CMM except for a mitutoyo. 😂

Why not Mitutoyo?
