Revox is very good and sounds somewhat different than Nakamichi. There are still places that service and repair them. Usually you can get one in good condition on ebay for about $500. I see no reason to use them instead of Nak.
Now, there are couple of Studer cassette decks that use better heads and all balanced in/out. They are rare and might be worth the attention. Expensive to buy and maintain.
