I always think it's fun to see what other runner's consider as their "must-have" favorite gear. Here is mine. If I link to something, just know that it is NOT an affiliate link and everything I consider to be my favorite I either purchased myself or was gifted to me by a family member (who purchased it with their own hard-earned green).
Current as of 1/13/14 I'm not comfortable using stock photos from each of these company's websites so I'll take my own pictures when I get a chance and upload them here. :)
Garmin Forerunner 620: I have this with the heart rate monitor, which I really recommend.
