For $400 extra you can get a upgraded console on the E3 Track. Hardly a bargain. True's M series ellipticals give you a lot more for the money.
LifeFitness decided to upgrade their elliptical lineup this year and made some real improvements. The addition of multi-grip handles gives you more options in your workout, otherwise it is very similar to the old X3. The biggest improvement, however, is for LifeFitness' bottom line. A massive increase in their asking price for this machine makes it a poor value compared to last year's models.
