The Numark AVM02 is a DJ-style mixer which takes both Video and Audio. It has better input and output capabilities than the V4:
AVM02 Inputs: 4 S-Video, 4 Composite
AVM02 Outputs: 2 S-Video, 2 Composite
V4 Inputs: 2 S-Video, 4 Composite (4 Preview)
V4 Outputs: 1 S-Video, 2 Composite (1 Preview)

I reviewed the AVM02 soon after its release, and liked it.
