here are a few that i use:
http://www.amazon.com/Eastons-Dictio.../dp/B001VEJ09Q
http://www.amazon.com/Matthew-Henrys.../dp/B00267T3JE
These two are excellente. The first is a bible dictionary. works with any installed bible and provides indepth defintions as you roll over text
The second is an easy to navigate bible with a built in commentary.
Really good
