I like the Garmin Touring Plus that I have. I have been using it for about 18 months. I use it as my daily bicycle computer, and I also used it on a month long tour of southeast Asia. The open source maps for southeast Asia that I downloaded on it were very good. The unit seems very durable. The actual battery life is 10-12 hours, but you can plug in an external battery stick if you need to use it longer or if you need to recharge it and do not have an electrical outlet available.
