Treadmill Recommendations

Hi all, long-time observer, first-time poster.
My home gym is nearly complete, with the last piece of the puzzle being a treadmill for conditioning. I would prefer an assault bike or rower, but my lady is a runner, and wants a treadmill. Compromise and whatnot. I figured since everyone here is smart enough to be here in the first place, this would be a great place to get some input.
Anyway, the must-haves are as follows:
• not manually powered
• at least 10mph top speed
• <43" overall width
• has to track distance

We don’t want anything else really, such as pre-programmed workout nonsense, though an electronic adjustable incline is greatly preferred.

So does anyone have any recommendations?
