I have just looked at the 2 products you mention, and both are similar in specs and price.
I have not used either but think that they will both do a good job of captureing and editing analogue video.
Most people tend to have digital camcorders these days and therefore there are not too many analogue capture devices available. With the new USB 2.0 able to transfer data much faster it does look as if the prices are coming right down. Previously you were looking at a couple of hundred quid for analogue capture.
Mark.
