There's a whole lot for Garmin going on under my roof: I'm having a blast with my new Garmin Edge 305, d has a Forerunner 305 on the way, and my dad likes his Nuvi 305.
With all this Garmin happiness, I feel like pointing out that you can get a pretty good deal on the Forerunner 305 on Amazon: $257.06 - $50 rebate = $207.06. The rebate ends on May 15. Garmin's own Web site lists these for $376.91, so that seems like a pretty good deal to me.
Why get a Forerunner 305? From my Edge 305 review you can get the gist of what it does, just subtract all the cycling features (e.g. cadence). The Forerunner 305 is like an iPod + Nike kit, except you don't have to get Nike shoes. In fact, you don't have to wear shoes. It gives you fairly accurate GPS maps and combines these with heartrate data for improved training. If most of your running is done on treadmills, something like an iPod + Nike kit is the better choice*, but if your running is in the great outdoors, you might want to consider something that doesn't tie to a particular brand of shoes. In fact, you could even use it cycling, snowboarding, or any other type of workout.
* You can get a footpod with the Forerunner, but that adds more $$$ obviously
