I searched ebay for all flashes with the low trigger voltages and
narrowed down my decisions. I didn't want to spend too much on all
of this. I ended up finding a Kalimar 175A that hadn't been bid
during all of the days it was posted, with a starting bid of $5! It
was new, but the guy was selling it because he had bought it for a
vacation, forgot to bring it, and the camera was destroyed while on
vacation. With 6 hours left, my bid held until the hour before
close, but I ended up picking it up for $8.50+$5.00 shipping.
Studying Michael Meissner's site and pictures helped me decide this
would would be a good option for me until I wanted to invest $$$ in
a really nice flash:

Next, I went to search for a lower cost option to the Oly cable.
The net was fruitless, although there was a custom cable
manufacturer that made the cable as well as an isolator circuit so
the 2100 could be used with even a high trigger voltage flash
safefly...but for a cost:

Since I was looking for a low trigger voltage flash anyway, I
didn't need the circuitry, so I went on to search ebay. It took a
while, since just searching on Olympus PC Sync Cord only brought up
the standard Oly cords, at not much of a savings from the $40 or so
plus shipping most places charge.
I ended up finding a custom cable, with the 5 pin Olympus plug, and
PC cord connection that most flashes use (mini/micro plug) on the
other end. It was listed for use with an Olympus digital camera and
Sunpak flash. I liked it because it wasn't a two piece cable. Again
the pictures on Michael's site helped me decide that this cable
would work. I picked it up for $25 including shipping.
My next stop is FRYs for a cheap $8 flash bracket that I saw a few
weeks ago. So, for less than $50, I think I'll be set for this
holiday season.
I am looking for a new digital camera, what I am looking for is a
camera that has at least a 5X optical zoom and a hot shoe for
external flash. I came upon the Olympus 2100. Noticed it has a
10X and a hot shoe. It stated the flash to use. When I noticed
the flash was 500 bucks, the bracket was 80 and the cable was 50
bucks...WOW give me a break. Is this the only flash you can use
with this camera???? You can't use any of these 40-80 dollar
flashes?
