OK, I'm sold.
I'll put in the purchase req first thing tomorrow. Should have it signed off some time in, oh, 2010.
Of course, once I do get Pro, I'll be bugging you for a modcp, and an option in the Mass Move to delete orphaned images (ones uploaded by users who have been removed from the system). Which I didn't see on that screen shot, unless I've gone blind again.
Thanks for the prompt responses.
