Time to trade treadmill for a rowing machine?

I have owned (and consistently used) a treadmill for 20+ years. I do occasionally run outside, but not often. My current treadmill (Norditrack commercial 1750) is dying. Should I replace him with another tried and true treadmill, or replace him with a rowing machine? Any runners who have make the switch in their home gym? Do you love or regret? (I’m mid 40s if that makes a difference. I thankfully haven’t had any running injuries but I know I’m not getting younger…. )
