    I am looking to add a 2nd strobe to my new camera (D70, Sea and Sea housing). I already have one Ikelite DS125.
    Should I just add another DS125 or should I consider the Ikelite 200 and use the DS125 as a fill in?
    The only reason I am thinking of the 200 is that while I shoot lots of macro, I am going to be shooting at F22 or smaller aparture to achieve decent depth of field so I am wondering if the extra power of the 200 might be more useful?

    I would stay with DS125 which has the latest digital circuitry and operates with the Manual Controller. The 200 is about 1/2 f/stop brighter, but will not be able to do the new DTTL and ITTL when (and if) we decipher this Nikon protocol............

    I use dual SS200's with my film Nikon N90s shooting strictly Provia. In a true "Macro" focus situation the actual f stop on either the 60mm or 105mm is 1 stop tighter (f-22 on the lens barrel is really shooting at f-32, f32=f45). Check your guide #'s of your strobe. If ALL you do is shoot macro than a second DS125 will be perfect . If you decide to try some WA shots however the 200 will give you a lot more reach. The 200's are reallyyyy huge beasts, however by the time you've housed an slr/dslr, what the heck is another few lbs.on the boat, UW they don't weigh a thing.

    Hmm, I shoot mostly macro but I am also getting the 12-24mm lens so I am planning on doing some WA shots here and there. I definitely don't want to carry 3-4 strobes and hope to use 2 for both macro and WA (if possible). I do like the idea of using manual controller with DS125 to give me a bit more control over the strobe and wonder if the 200 might be a bit too powerful for macro or supermacro.
    With OlyC5050 at F8, ISO64 and 1/8 power on the DS125, I sometimes already find the strobe a bit too powerful and have to keep moving the strobe back (with diffuser installed). Now with minimum of ISO200 on D70 and F22,F32 etc, I wonder if I will run into the same problem I had with DS125/C5050. I guess I should try to find Ike's table on the guide number and distance/exposure thingy again. It is probably somewhere in my messy desk at home.
