Tri-State Camera has the Nikon SB-910 flash for sale at $439 this is the
lowest price I have ever seen. Here's the link: http://iway.org/9572631
.
For those unfamiliar this is the flash that replaced the SB-900 as the top
of the line flash with the same power and an improved thermal protection
system and improved menu system.
I've used Tri-State many times over two decades and have had very good luck
with them, but YMMV.
