Hi,
I'm looking for a cheapo strobe after falling on 2 epoques ds150 which stopped working after 15 dives (no flood guaranteed 
).
The Bonica seems fabulous - the neon head goes for 100 USD at B&H. Does anybody know if the screw is the same size as the epoque's ? That way I can re-use my existing tray and arm.
The Bonica XP seems to bring something like TTL - how on earth does that work with no communication between the strobe and the camera? At best I can understand that the strobes reads the distance - but that simply means that each time I change aperture I have a problem... Seems like a headache producer more than a feature 
Any experience on that?
Otherwise I'm open to any other cheap recommendation. BTW - I use a Canon S50 underwater which I highly recommend!
