We installed one in our showroom on Friday and I was impressed. (I'm not easily impressed by the way.) It performed pretty well. The speed was acceptable....actually the speed was real good on a typical blueprint. The image quality is good enough for what it is. Just don't over-sell the image quality.
Two other thoughts:
The box the thing ships in is enormous....
The machine was a time bandit for our guys to unbox and set up.
