This will be no surprise to one individual in this thread...
I use the CA-1 day in and out for all types of display devices. The cal files issue is really not an issue at all. Progressive Labs make files based on popularity of products in the market place. If you are looking for a cal file for a Projecta-Vision DLP (the first commercial unit, not something Runco is going to market under that newly acquired marque) then don't expect a file (get a TVS optical comparator and practice!).
However, if you are going to go into business, Plasma files, for instance, are readily available for the major glass makers from Progressive Labs.
You should still hone your skills and follow-up your work (as a means of developing your "chops") with optical verification. So, I would not make the availability of files a factor in your buying decision. The accuracy of the Progressive Labs software was a key issue in my decision.
I am certain that the folks at Colorfacts will be eager to discuss their salient points, as well as Sencore.
As with any purchase: Caveat Emptor
