Try to get a model that will record and play back S-VHS-(as well as the substandard VHS). That way there won't be such an astounding image quality difference between the DVD and the videotape. At least the SVHS is a lot better than the regular VHS. DVD makes regular VHS look just terrible -by comparison. /ubbthreads/images/graemlins/icon15.gif
And that way, of course you'll always be able to record OR play any VHS or S-VHS tape to it's maximum capability.
You will have to look a little for such a model, as they are not that easy to find, and they are a little more expensive when you do find one, but worth it-IMO. JVC and Mitsubishi make a couple of those models.
