My DVDO Edge has an ABT2010 as well. Personally, I think it's quite mediocre. The scaling is mediocre, especially for 240p stuff that I have (I have old game systems e.g. Sega Genesis, SNES, N64, etc.) - a lot of ringing for 240p, and still noticeable for 480p IMO.
It is very weak for noise reduction. Has almost nothing in that area. VXP, HQV and QDEO all have significantly better noise reduction than the ABT.
I'm not really disappointed in its deinterlacing - I rarely see artifacts. But game mode (which I need for some games) can product an unstable, annoying picture.
"Vintage" is good for wine, not for A/V equipment.
