I have a Tascam 488 8-track, and it's always been reliable. Had a few problems with the stop and play buttons being a little finicky (it was even repaired once.. :-\) and the 8th track sometimes will or won't work. But it has GREAT quality, even now being about 13 years old. It has served me well, and still does, I'm otherwise very happy with it! 🙂
