HUGE digitizer LCD?

What’s the general consensus? These are some of the only ones I can find like this. I got to use a ITI VisionMaker for about 30 minutes one time, but they have since gone out of business. Does anyone else know of another LCD digitizer that is big like this?

Anyone have any thoughts on them (crappy, good, phenominal, etc)?
