Here are two styles of the K731. I like both (what's not to like?) but the "Colonial" style with the shorter legs to me, looks a bit more classy. I'm not much into the "TV console" look, which is what Zenith was after I think.
Other variants of this radio, the T2542 and the T350 are nice sets too. In fact, I have a T350 playing on my desk now, and it's unusual with a brushed metal faceplate that stretches over the dial and the control knobs- neat.
