Turns out it was the IM1000, the older version of the current IM2000.
At first I was disappointed since the bench design isn't as versatile, but after spending 10 minutes seeing how the bench and accessories integrated, I bought it.
This thing is built like a tank and it somehow takes up less space than my Bowflex Ultimate 2. With the pec dec on the back of the unit, I was able to angle it into a corner, still have plenty of space to get to the pec deck and to load weights.
So far I've only done presses with it, and a few demo squats and leg presses and leg extensions but everything felt good. The geometry of the leg extensions and the lack of cable slack / proportional resistance of the bowflex made the leg extensions MUCH easier to do correct form yet do higher weights.
Since it uses a cable attached to the main smith for cable work, the minimum cable exercise is 45 pounds. This hasn't been an issue, but if I had purchased this machine 2 years ago, it would have been more limiting.
All the older accessories still interchange with the new superbench, so I can upgrade that later if i want without repurchasing all the accessories.
Overall, very simple, very solid, great look. I'm VERY happy.
