Deal or NO Deal

[Colt1917]

Last Friday I found a post on craglist for two metz's flashes. One 50MZ-5 and one 76MZ-5 both in like new condition, in fact the 76 was still in the box. Took the deal and can't belive the light quality off these flashes. Makes my vivitars look like a key chain light. So what I would like to know is for $550.00 was this a deal or not. They both had the standerd 301 adapter so I've got my SCA 3702M2 on order. But still in auto mode on a K100D super I can't belive the light. Ya Me. And by the way that was my first time to craglist. Did a goggle serch on metz and about 16 page's down I found the add.
