I am looking to rent an underwater housing for a canon xti (400D) for a week of diving. I assume the ikelite model 6871.40 is the most popular one. Would love rent an external flash to go with with it. Not sure if anyone knows a company who rents these, or would be happy to help you pay for yours a bit by renting from an individual. If anyone can help me it out it would be majorly appreciated, we can negotiate a fair price etc.
