Reel-to-reel tape is the ultimate hair shirt medium. You can't find any particular track in the middle of the tape, the tape can break or shriek or has had the treble shaved off by being played via magnetized heads. As a mechanical device, a tape deck needs regular maintenance by someone who really understands these beasts. Parts are rare or nonexistent. And you want to compound all this by buying a TUBED unit, and you don't even have any tapes.
I say go for it.
