this one is looks really nice
But seriously I have 2 of them, one is a Life Fitness 97t which is a commercial machine my brother has a T5 from life fitness that is also very nice and more of a residential machine... My wife uses a Nordic Trac that has all kinds of fancy features hers is about 4 years old but its one of them jillian models, 40* up incline and 5* down incline... I like my life fitness commercial machine its built to last forever, I weigh 300 lbs sometimes so need a good machine if I am going to be running on it..
heres my machine
Integrity Series Treadmill (97T) | Life Fitness Its a little more expensive than the others I paid $6700 and they bought my old life fitness for $2200 so after tax and my trade in it was around $5000... They have them up to $10000 but it only adds smart features like youtube and a tv, I have a tv in the gym so I didn't need it... but they are pretty nice...
