I've been looking at those hand helds but I think I'll put one on my Christmas list though that limits the price to under $200.
Speaking of batteries I've standardized on Sanyo Eneloop because of the low self discharge I can leave gear sitting in my bob and have it ready to go.
I have a Maha charger after finding out a lot of chargers don't fully charge batteries and am converting from the cig lighter type of plugs to anderson power poles due to their smaller size and better connection.
