I've been pretty happy with this little device, the
Elgato EyeTV 250 Plus. A simple piece of hardware that comes with an app which can edit and save as a number of formats.
It was originally designed to provide television on your home computer, but the coax connector also doubles as a VHS input.
There are a few tricks to editing the files, but just getting the files on your computer is a piece of cake.
The files will have an extension of ".eye", and need to be imported into something else (they suggest editing with Toast, but there are other options as well). At least while learning the app and its' features, I would strongly suggest making a duplicate of the .eye file, and tucking it away for safety, in case you need a back up. The app itself has a quick-and-dirty editor that allows you to edit and export individual tracks if desired, which works fairly well, once you get the hang of it.
There are probably some other good products out there, but this one has worked pretty well for me, so I don't mind giving it a little plug.
