Aloha Judy,
Have you got a strobe yet? If not, did you buy a used camera because; you had to have a 5050 but its out of production, you got a really good deal, you wanted AA batteries, a combination or some other reason? If budget was a consideration consider used strobes also.
Two years ago, after weeks of research, I bought a reconditioned 5050, as well as a PT-015. At the time I felt it was the best camera in my budget (still feel that way). After years of Nikonus V, I already had two Ikelite SS200 PhotoCase strobes. I could not bring myself to spend nearly a grand on
more lighting, but could find little info on using older strobes with digital cameras. Eventually, I gambled on the Ikelite TTL Slave Sensor (orange), the best $150 I ever spent.
IMO, the prices are pretty high for scrapbook photos. Even being a cheapskate my costs were; 5050 - $375, 5 year warrantee - $50, PT 015 - $180, CF 512 Mb - $95, INON WAL - $350, TTL Slave - $150, shipping to Hawaii from 5 vendors and a bunch of rechargeable AAs; well over $1300 without the strobe! I am still happy with my rig, but factoring in the $1000 I originally spent on the SS200 and $80 for a new xD 512 Mb, Its a $2500 set up and I better be happy with it.
I am still learning how to use this system better. My starting point was the My-Mode settings. This link is for a tutorial on that, a must for Oly shooters.

My current favs are 64 ISO, F4.0, 1/100th for shallow sunny, 100 ISO, F5.0, 1/80th deep or dark. Just like the older strobe issue, I recently discovered
on my own that I could shoot raw continuous
with strobe. I guess the recycle on the new DS125 is not as fast as my old SS200, because the only continuous strobers seem to be using SHQ jpeg (slightly slower). Or maybe the SS200 is brighter, as I mostly use 1/8th power (occasionally 1/4th), even with my coffee can lid diffuser.
Its not just the cost, there is also considerable process time involved in my underwater images. Converting from raw to tiff, adjusting levels, color, contrast, brightness, resizing for web or printing, sharpening, saving as Jpeg. If you have Photoshop CS2, you can batch convert and process, but I find most images needs different tweaks and CS2 has even more options so possibly more time.
Good luck with whatever strobe you get, any system will take great shots shooting within its limitations. More money = less limitations. Shoot, learn, shoot some more, learn some more, and please do the environment a favor; get rechargable AA's.
