Buy a real commercial elliptical from LifeFitness, Precor, or Cybex. The PRO3700 is the proverbial trojan horse of commercial ellipticals.
The PRO3700 is Octane's commercial elliptical that you can put in your home. For my money I would buy a commercial elliptical from LifeFitness, Precor or Cybex. They are true commercial machines. Octane is just a pretender in this market, go and buy the real thing if that's what you want.
I have a 12 year old Octane Pro 3500 I bought used. It works awesome. Heavy as a horse (320 lbs ). For what we use it for in our home it is more than enough. I don't see what the problem is with the website review.
