Kool. Revox and Otari are both GREAT makers.
You might consider that Otari still makes parts, and, I dunno about revox? anyone?
I'm glad you're going for it. My first priority for a mixdown "unit" is an Alesis Masterlink. ............ I know, it's digital, but hey, it's a hard disk recorder, and CD recorder all in one, and one way or another, I need something that will record CD's w/out the involvement of an 1/8" stereo plug into my computer's sound card. ick.
Then I may try to find an Otari later on, budget and priorities permitting.
Good luck!
