Well, my kiddos are getting certified on our next trip so I'm going to downsize to a more compact setup so I have the ability to be more helpful with the kids in the water. My wife will probably appreciate it too as I'm a terrible dive buddy with my face behind the lens all the time. Anyhow, here is my current set up which I am looking to sell. Everything is in great condition. The only missing part is the eyecup from the camera body. I took it off for use in the housing and I've lost it somewhere along the way. Everything else is in great condition.
$995 for the items listed below
Canon Rebel XSi 450D with 18-55 standard lens
1 Canon Battery with Wall Charger
SeaTool Housing (purchased from Reef Photo, MSRP of $2,699)
Standard Flat Port for the 18-55 lens
Ikelite DS-125 Strobe (plus cable and charger with international plug adapters)
From what I have seen, camera is valued around $150 at this time, strobe around $350, and I'm asking $495 for the housing but can't find any of those for comparison. It is definitely a high end and very durable housing which you'll be happy with. I also have an Ultralight Arm System which I'm willing to part with if necessary. But I'd prefer to keep those parts for use with my new set up. First photo shows everything for sale. The setup photo is with the arms and focus light which I will only sell if you really want to get the whole package for immediate use.
