[quote name='game_fanatic']Yikes, I'm not sure 8-AA batteries and the C9000 charger worth 4 times the amount as the Eneloops package mentioned in this thread. I'm sure that package is better overall, but I just don't think they're 4 times better.[/QUOTE]
The batteries are definately not 4x better, but they are a pretty good deal in the combo pack (You're paying about $21 for 8 batteries)
The charger is definately much, much better, easily offering 4x+++ more features, but it kinda depends on what your needs are. If you just want to recharge the batteries and replace them when they eventually run out, then pretty much any decent 1hour+ smart charger will do the trick.
The C9000 is more for people who want the extra features offered by it, such as discharging, cycling and break-in modes, as well as people who want to know how healthy their batteries are. It can also be used to restore bad batteries (within reason) and it might save you some money in the long run (probably never save enough to justify the original cost, though)
So, I guess it's worth is dependant on your needs.
