Treadmill for home gym

I’m looking to purchase a treadmill for use in my home gym. Which treadmills did you enjoy and which did you not like?

To give you some context, I run around 70-80mpw. I don’t need to go too fast (most runs are between 6 and 9 mph), but I do tempos at sub-6 mph on occasion, so something faster than 10 mph, maybe 12 mph tops, would be ideal. I usually run outside, but due to air pollution, snowstorms, and the fact that I can’t go to the gym because of covid, I’ve/we’ve decided it’s time to acquire a treadmill. Wife would also use the treadmill frequently.

I have a Lift Fitness SE3 I wouldn’t buy anything else I love it. On the pricier side but great machine!
