best Marantz tuners?

I have a Sansui TU-717 tuner and love the sound. However, I love the look and build of the classic Marantz stuff. Some of their older tuners, with scopes for example, look so great. I have a 2250B rcvr and it is nice.
Anyway, I am thinking of going for a classic Marantz tuner.

What would be the short list of their best tuners?
Would it be a step up from the TU-717?

Thx,
Rob
