@rbtstock before you buy anything you need to figure out what type of tapes you are going to play back. 1/4 track commercially released tapes, 1/2 track tapes, what speed (3 3/4 , 7 1/2, 15. 30), Etc.
There are a few decks that will take care of the track configurations, but not all the speed configurations. once you determine what types of tapes you are going to playback, then you can narrow down what type of deck you are going to search for.
