I echo the thanks and gratitude of michealsutton555.
I, too, am beginning my strobist journey and with your in-depth, articulate and very understandable explanations you have greatly improved my education and positively influenced my decisions for flash purchases.
I was approaching this adventure much like tulasi- trying to put together a system on the cheap w/ odds and ends of used flashes, work-arounds and compromises (no offense intended tulasi).
I will have to wait a little longer to save for the proper Nikon strobes but there are plenty of other photo and lighting projects I can tackle in the meantime.
Many, many thanks for sharing your knowledge. Nikonians is the greatest.
