Your Sunpak handle flash looks to be an up-date(?) over the 3600 A/T.

I think I am going to wait until I can find a Nikon unit from the mid to late 80's with a bit more power- something in the G/N 40 (meters) range. I don't really need all the automation of I-TTL and auto focusing heads and reflectors- when it comes to flash, I usually end up going to full manual operation anyways.
