imaging source USB capture

Anyone used one of these?

I need to get an analog composite signal in with as little latency and overhead as possible. This seems like the ticket.

I tried an easycap device that someone mentioned in another thread but i think the driver is a bit flaky as it grinds TD to 1fps or less near halt.

im open to other suggestions too…
