How does a Faroudja DVP-1000 stack up today?

In a system that is RGB output based, is the PQ of the newer scalers that much of an improvement? I have an NRS and have run into limitations due to source changes. I have a line on a reasonably priced DVP-1000, which would seem solve my new source issues. If you want specific info on my setup, look down in the posts to one on CRT/Plasma processor recommendations.

The DVP-1000 will process HD inputs, including 1080i, to the selected output rate of up to 1080p, although my plasma is 1280x768 and my 8" CRT would probably max at 960p. Even if you do the NRS universal rate upgrade, the maximum output rate is 1024p and it will only process 480i inputs, everything else must be passed through. The DVP-1000 will also process DVI progessive inputs. The 1010 seems to add HDCP compliance to the 1000. At least this is my take on it from the manuals. Does processing of HD inputs improve things or add a step that can actually degrade the signals? HD sure looks good passed right on through to my projector now, whether 720p or 1080i. Maybe I don't know what I am missing.
