Amazon offers the Garmin Vivosmart HR Activity Tracker in several colors (Black pictured) $79.99 with free shipping. That's tied with our February mention as the lowest price we've seen for a new unit. (It's the best deal now by $20.)

This water-resistant tracker monitors heart rate, calories burned, distance traveled, steps taken, stairs climbed, and hours slept. It features an LCD, and vibration alerts for calls, texts, emails, and meetings.
