Unless he's rich. I know a rich collector who wouldn't bat an eye at dropping $650 for 10 Darktroopers.
And at this point, considering that there are fewer and fewer things that Hasbro doesn't re-release OR improve on at a later date, my statement still stands. I'm not bragging, but I could swing dropping $650 for 10 DarkTroopers my self, but in two years when the figure comes out a different way, I'd feel like a supreme IDIOT for dropping so much money on something that two or more years later would have only cost me $100 (say if the figure is released individually carded). It all comes down to what you're willing to spend and live with, I guess.
I have had a couple of instances over the past 15 years of collecting this line just like this...
I once dropped $400 for a graded set of MOMC WalMart Saga Cantina Wave 2. I have all of the EP1 foreign releases with Battledroids and Pit Droids - I even bought some so I could open up the pit droids. At the time I made both purchases, they
seemed like a good idea. In hindsight, after the K-Mart Cantina 3-pack Sets AND the 2007 Saga Legends line, both of those purchases became downright silly and for me the only sollace I found in making them was that a majority of the purchases left me with hard-to-get items in my MOC/MIB collection.
Granted it was almost 10 years, but even the Darktrooper from the first EU wave in the late 90's found it's way out again - and I know a couple of guys who dropped a lot of money on eBay to army build that trooper.
So anyway, my point is that if the history of this line has taught us ANYTHING, it's that a figure that may be hard-to-get (or expensive-to-get) one year, ends up being easy to get the next (or a couple of years later).
