I have a (sort of) used Ikelite Underwater Housing with E-TTL for Canon EOS-20D Digital SLR Camera. The housing is basically brand new and yours for only A$800.
Previously broken case which has just been returned from Ikelite with new clear case part, completely refurbished and reconditioned buttons and dials, and upgraded electronics. Not literally new, but about as technically new as you can get otherwise and has not been in the water since being returned.
This compact dSLR housing system is very realistically priced, and costs over A$2500 to replace. If you are looking to get into underwater photography, or need a new housing for your Canon 20D you can't beat this.
Please contact me if you have any questions.
