My initial suggestion, do not buy an external comb filter until after you have seen something you don't like about the built-in comb filter.

The Camelot VPS-1 is a "two dimensional adaptive" comb filter which categorically is below the "three dimensional motion adaptive" comb filter in performance. The VPS-1 should not show any dot crawl or rainbow swirls on true horizontal or vertical edges but will exhibit some swirls on finely spaced diagonal details.

Where the VPS-1 outperforms 3D comb filters is when the 3D is not truly 3D. I have seen a "3D" comb filter that is so mediocre that its first two dimensions (used for moving subject material) are really not two dimensions. Particularly when something detailed is still and starts to move, you see it become noticeably blurry. On this set a still test pattern (which uses the third dimension) excluding laser disk still frame (which does not use the third dimension) shows a superb picture.

Also (as far as I know) do not use a CLD-99 with any external comb filter if you can avoid it. This and a few other high end LD players do not have a native composite output but rather re-composites the S-video to become the composite output. The CLD-99 has certain noise reduction and time base correction (for purer color) that is done on separated Y and C subsignals. When you use composite output to a VPS-1 there are two comb filters in the signal path. Comparing the picture quality, the S-video direct from the player will then always look better.

As soon as anyone else finds or invents a better comb filter than the LD player has, the forcible use of the built in comb filter is a big drawback to that player.

I am not sure about whether the CLD-704 also re-composites its S-video to become its composite video output, or whether the CLD-99 has an option to switch it off and deliver native composite video.
