I have done a lot of research re: analog to video converters........and I have read a lot of reviews covering these type of stand alone boxes. I bought the Canopus ADVC-100 and I have had terrific results with this converter box. I am sure, that the Sony and the others you described are capable units as well, but, the Canopus device was under 300 dollars and it has a variety of input ports on the front and back of the device and supports locked Audio/Video capture. I was told that certain Sony Digital 8 camcorders also handle analog capture just as well. good luck.
