Great app – Guru Maps - Navigate Offline Review
It's fast, the maps look good, and the features are useful and appropriate. There is not a lot of fluff. Downloading maps is fast and convenient. A big feature is having the maps on the phone (so you don't need cell network access).
I'd suggest purchasing the "all-in-one" feature pack.
