Drinking Frog makes a very good comment. Nothing is a good bargain if you don't use it, and drying racks are cheaper.
You just have to experiment and find what works for you. I was a serious distance runner for nearly 25 years, running over 31,000 miles, finishing in the top tier of marathons and shorter races. I was given a nice treadmill, a tier above this one, but I rarely used it, less than a hundred miles. I didn't much like running indoors at all, and would only do so when forced by weather, which even in midwestern states doesn't happen all that often.
My knees eventually gave out, with arthritis running, like most families, in mine. During my recovery from double knee replacement, I discovered that I loved, absolutely, the recumbent bicycle. I bought a Schwinnn 202, and have put over 20,000 (fantasy) miles on it. I ride 20 miles five days a week, pushing my heart rate up to about 150.
Now, it might be an elliptical, a treadmill, a bike or a recumbent, but those of you who must or need to exercise, check out the options before making a purchase. See if a gym near you has a trial and use it. Maybe the gym and its options are right for you, and maybe you will fall in love, so to speak, with some other machine, but you owe it to yourself to exercise your body.
BTW, I'm 65 years old, 6 feet tall, weigh 168 pounds and my heart beats about 45 times a minute when I'm relaxing.
