I've been using a Garmin edge 800 for years. Yeah the screen is small but I'm used to it. I just need to zoom in when trying to navigate in a city, but out in the countryside where there are fewer streets it's no problem. I bought my first one used and when it finally died I just bought another one instead of upgrading to the 1000.
I thought the newest Edge that came out (1100?) was supposed to have incredible battery life. A friend has the 1000 and he loves it. Big screen, short battery life though.
Edit: But yeah, any issue with just using your phone? Assuming you'll bring one with you anyway, waterproof handlebar mounts aren't expensive, and there are plenty of apps for routing and ride tracking.
