Precor M9.35i
$4,000 / Programs: 22
Say you like to vary pace and incline frequently during workouts. With the M9.35i you're not forced to press the same button again and again. Its touch-sensitive buttons respond immediately--a nice feature when running fast. We also liked the lap-track visual on the console for speedwork and 5-K and 10-K distance-based programs. Since the belt is shorter than others (57 inches versus 60), the M9.35i is better suited for shorter runners. precor.com; 800-477-3267

True Z5.4 HRC
$4,000 / Programs: 14
Our testers consistently found the Z5.4 to be quiet, soft, stable, and smooth underfoot. They also liked the bright display and found the programs easy to navigate. Plus, you can adjust the belt's cushioning to one of 12 preset levels with a convenient side lever. (Another nice feature of the belt: it's wider--22 inches versus the standard 20.) The handrails extend only slightly away from the console, so most runners won't hit them with their arm swing. truefitness.com; 800-426-6570
