In order of 3:2 (progressive de-interlacing) performance
Poor- Mitsu internal
Better - Quadscan (genesis)
Best- DVDo Pro with Sil503
Scaling performance
None- DVDO does not scale, only de-interlaces
BEtter- Mitsu internally takes 480p up to XGA
Best- Quadscan

In order of quality
Poor- mitsubishi with no external device
Better - Mitsu with DVDO de-interlacing to 480p
Best- Quadscan scaling to XGA.
You will note that your DVDO probably has better de-interlacing than the Quadscan alone, due to using a better chipset (s503 vs Genesis)
However, the DVDO does not perform SCALING at all, while the Quadscan does (in your case you would scale to XGA).
It is because of the scaling feature that I would recommend the Quadscan over the DVDO.
Does this help?

Is it only assumption? I know the scalers in a few different LCD monitors (IBM 16" Ezio 18") I have are absolutely terrible(it basically does Pixel Stretching(nearest neighbor algorithm I guess.) But are internal scalers on a $12k MSRP projector that bad?

Also, does quadscan do Time Base Correction? Iscan Pro does not, which causes havoc with my projector(or any other LCD monitor I hooked up to.) Getting a TBC VCR (JVC 7800) helped with image skewing, but I get frequent blankouts, from what I don't know. Too much of this trial and error buying is making me tired.
