What is your video capture card like?

I’ve been looking for a state of the art video capture card so I can do a lot of things with it and have looked at three products: Matrox RTX100 Extreme Pro, Pinnacle DV500 and WinTV PVR 500.

I was wondering, have any of you experienced either of these that can give an opinion of them? I have seen cheaper models but I have a load of VHSs to convert so this convert on the fly business may well save me quite a lot of time!

Any help greatfully appreciated.
