Thanks for the info. I did look over the table which was helpful.
Is the YS-27 being "slave" only a big deal? I understand the YS-27 doesn't work the the A setting or P&S options on my camera and there are 3 less settings compared to the YS-110. Also I noticed the ligting is 85' x 105' compared to the YS-110 at 105' x 105'. I am thinking the $300 extra for the YS-110 would not really be worth spending right now.
Is there anything else I'm missing?
Also are the Sea & Sea tray and 5.1" arms good to have or are there problems?
DvrRick,
For where you are at the moment, I don't consider that the extra $300 is worth it...IMHO.
That extra $300 could buy you another YS27DX and then you could really get into strobe work.. 
As Jim said, make sure that you get the S&S fibre optic cable for the YS@&DX. I think from memory that it is called "Fibre Cable'L'."
As for the S&S arms and trays, I consider them to be overpriced 'junk' when compared to the gear available from ULCS. Don't even think about it. If you want some "real pretty" lookin' kit, then have a look at the 'Athena' web-site. They make some outstanding equipment for the Olympus 5060 and and the Olympus PT-20, and is second to none..IMHO.
But then again, you might want to ask someone who knows what he is talking about... 
HTH,
Bruce...
BTW, I almost forgot...
When using your 5060 with slave-fired strobes, set the internal flash to 'SLAVE', as this will remove all the pre-flashes, then the strobe can fire on the first flash, which will be the main flash. If you do this, you can also reduce the power of the 5060's main flash, via the menu, to give you extra battery time. This is necessary for two/three dives a day...woohoo, it's all starting to come back. I'm not brain dead after all...
