Microsoft Store offers the Garmin Forerunner 110 GPS-Enabled Sports Watch, model no. 010-00863-00, for $89.99 with free shipping. That's tied with our mention from a month ago as the lowest total price we've seen. (It's also a current low by $25.) It also features a high-sensitivity GPS receiver, USB interface, built-in rechargeable lithium-ion battery, and ANT+ heart rate monitor compatibility (heart rate monitor sold separately).
