I Need Suggestions For a Flash Unit (or two, or three...)

[Glen]

Hi,

I think Pentax has just recently introduced a flash unit designed with the 
digital SLRs in mind. There were also a couple of existing Pentax models 
which were supposed to work pretty well with the *istDS. Then, I've found 
that Sigma makes a couple flash units which should work pretty well on the 
*istDS. Are there any others worth considering?

I'm interested to know what flash unit people on this list have used on 
their *istDS cameras, and which ones they recommend. The Sigma units could 
save me some money, but I'm not sure what I might be giving up.

I think the things that are most important to me are high power, and the 
ability to use multiple flash units with relative ease. I might even 
consider getting some studio monolights, if I could find some inexpensive 
ones worth buying. I guess what I really want is something in between the 
typical studio strobes and simple on-camera flash. I need something very 
portable, but with the ability to easily use multiple flash units.


thanks,
Glen
