GPS/HRM....?....

... so I've been doing a lot of running and getting out more. The guy who's been helping me get in shape suggested I get a HRM. I used to have an old Polar, but it's gone missing or is somewhere that I can't remember at the moment. In any case I started looking and thinking about electronic toys. I'm already way behind the curve and need a new digi cam, but maybe Santa will bring that if I'm good. So now the HRM comes up. I can get a cheap one from a mega-mart type place cheap, but I've also been thinking about a GPS type unit since I'd like to start exploring more of Austin's off road and don't want to constantly rely on others... so what I'd like is a GPS with up loadable maps and a HRM. The Garmin Edge 705 looks like it would fit the bill, but is quite pricey and bulky for off the bike jaunts. The Garmin Forerunner 305 will give me the HRM and down loadable GPS, and will work if I'm lost to get me back to the beginning, but lacks the ability to upload maps. So then I start thinking maybe a GPS and an inexpensive HRM. I like the DeLorme PN-20 (free maps) and since a new model is scheduled to launch any second they can be had used for under $150...

So to those who are GPS/HRM gadget geeks speak up.
