Back in the day, the Panasonic AG 1980 was great for transferring VHS to digital. The problem with buying a used one today is that because they were used professionally, it will most likely have lots of wear on the heads. The best bet today is to find a used consumer JVC S-VHS deck. The S-VHS output provides a superior transfer and most JVCs include a software "edit" switch that provides the cleanest signal possible. Some of the higher end models even include a TBC (time base corrector) that will help with some tapes. Since these decks were not used professionally, your chances of finding a clean, low hours model is much greater.
