I have had a 305 and now have a 705. I love these computers. The best bang for the buck in the Garmine line is the 500. The 500 has a better screen than the 305, is smaller and I think cheaper too. The 705 is great if you want to create a route on your computer and have the 705 give you turn-by-turn directions; of if you want to enter a location and have the 705 give you directions.
