I'm not saying this thing is perfect - but it works fine. However, it suffers from the same problem that most other SB-105 owners have experienced: sometimes before a dive, the power doesn't come on, and you have to jiggle the battery contacts. I've partially remedied this with the same trick many other SB-105 owners have - an o-ring between between the battery compartment and the door puts pressure on the contacts to the batteries. I bought it used in 2005 for $250, and have used it on less than 60 dives since then - primarily as an off-camera slave for creative shots.
Includes diffuser and 1" ball adapter.
$50 (I know my website says $70 at http://www.aquaexposure.com/AquaExposure/P...S/PRODUCTS.html but yes, I'll sell it for $50) (plus $5 shipping in the Continental USA)
