I ended up getting the EV718. I liked the ability to have the controls at your thumbs while exercising. With the EV716 you have to let go and try to poke buttons on the console to change your workout. Now I just need to figure out how to carry the darn thing to the bedroom. Man, is it ever heavy! Since it operates virtually silently, I can go along with her having it in the bedroom rather than down in the gym.
That brings up my reply to Michael; I have a complete full free weight gym already. I only worked out with free weights in college, so that is what I prefer. Besides having a professional Smith machine, I have a squat rack, hack squat machine, 4 benches (flat, incline, decline and 2nd flat), bench cage, high/low machine, calf raise machine, leg extension machine, cast iron dumbells from 5 pounds up to 150 pounds in 5 pound increments, and several other specialty pieces. I have a Stairmaster Stepmill, a treadmill, and now this elliptical machine for cardio. Heck, I even have a drinking fountain in the gym so I don't have to carry around bottles of water.
I need to work more towards the aerobic stuff now rather than heavy weights since I'm beginning to get older. My joints just won't take what they used to. Although it's been several years ago, I benched 360, squated 610 and dead lifted 660 in my last powerlifting competition. Since I have a 17 year old son who is now getting into lifting, I'd like to at least get back to those numbers. I think I can do that. I've admitted to myself that I'll never get back to my peak strength. That was over 20 years ago and far, far away in what seems like another life...
