Hi, I currently have a Sunpak 444D flash, a DX-8R ring flash, and one PT-2D module. I'd like to get another Pentax module, but the PT-2D modules are somewhat hard to come by, whereas the PT-1D modules are pretty easy to find. The Pentax bodies I'll be using these flashes on will be the ZX-5N (in TTL mode I figure) and K200D (in Auto mode I figure). I've tried to dig up info on what I'd loose with the PT-1D modules vs the PT-2D modules, but haven't come up with anything - anyone have any experience with this? Thanks in advance.

I've never used Sunpak with Pentax TTL so my answer may be wrong (not the first time nor the last time, mind you ): the only difference is that PT-2D supports TTL, PT-1D does not.

To me there is no difference - I use Sunpak flashes in either auto or manual mode.
