Mikey- You are posting some inaccurate information. First, Alien Bees are not the least expensive studio strobes in the testing. That honor goes to the more consistent Photogenic.
The only place I could find a price on the Photogenic 320B was at Adorama where it still sells for more than a B800 (although only $20 more) :
The 160B sells for $45 more than a B400:
There may be better prices but I couldn't fine them.
I did finally find them on B&H's website. Their price is lower for the 320 (They didn't list it as a 320B.)
I'm done kicking this dead horse.
