My wife and I bought a Precor M9.20s model long ago (over 10 years). It was expensive - about $2.300 or so as I recall. But after 6,500 miles it's only required lubrication. Zero parts. I flipped the deck over about 2000 miles ago and it's been going strong since. It's not the quietest machine around but after 10 years I could have used up 5 lesser machines.
