Hi Gang,
I'm looking to buy a decent general purpose flash unit for my D80 on a really tight budget of <$100.
This one and
this one look interesting but since I know nothing about flash I'd appreciate any comments.
Also, what does "Guide No. 92'/28 m at 50mm" mean?
As always, thanks for your help.

If you can find a Sunpak 383 Super flash it's a great auto/manual flash with both bounce and swivel capabilities. The Vivitar 285HV is still somewhat available and it has a decent auto/manual capability with bounce only capability (and it's often recommended by "The Strobist" site.)
There is an alternative in the Vivitar DF400MZ Digital TTL Shoe Mount Flash for Nikon i-TTL:

It gets fairly good customer reviews, has bounce and swivel, and both manual power settings and a slave function, making it pretty versatile. I have been looking at this flash in the Canon mount because it also has gotten fairly good user reviews.
A "Guide Number" (GN) is a measure of power output that allows comparison between different flashes. The "at 50mm" generally means with the flash zoomed to accomodate a lens with a FOV of a 50mm lens on a full frame 35mm format camera. As flashes zoom further out into telephoto FOV they generally have a higher GN because the light doesn't spread as much.
If you use a flash in manual mode you can also use the GN to calculate the correct aperture per distance with the following formula:
GN/distance=f-stop (assuming ISO 100)

Unless some one has a better suggestion < $100, I'll probably go ahead and order it later this week.
Thanks again.
