I received my Forerunner 205 last Monday and have been running with it all week. The signal is so much better than the 201 ever was. I even have a signal inside my house.
When I first uploaded the info from the Forerunner 205 to TF, It said the memory was empty. This is when I realized you need to hit the reset button first. Once doing this the info uploaded very quickly.
When comparing the 205 track to a previous track using the 201, I was really impressed with how smooth it was, not zagged like the 201 alway was. I had the 205 set to post a track point every second. The points exactly followed the path I ran, even when I moved to the far side of the path or road due to traffic, it showed exactly on the map. Awesome!
If you are questioning whether you can justify upgrading to the Forerunner 205 or 305, just do it, you won't be sorry.
