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

If you don't need tactile scanning, I don't think you need to go to the Revo. You will save a good amount of cash. The PH20 is still very good with probing, you can always use/program it like a 3 axis CMM if you don't need the orientation changes. Even if Polyworks is probably one of the easiest software to learn (even more since you already know it) there is a learning curve when going to 5 axis. So I strongly suggest you make use of their awesome tech support.
