Being as I just purchased my Maha recently, I voted no. However I will not say never...
I already tossed the idea around of getting another charger if at a minimum just to have something to charge with when my Maha is tied up on a break-in..etc.
I don't need the li-ion capability, I am strictly AA right now, however I do like the C and D capability the 3000 offers though.
If they would upgrade the app on the NC2500, I would consider going with it too. I don't care for the noisey fan...so I would be interested to hear what the 3000's will sound like.
All in all, if the 3000 comes close to what it has been hyped up to be, it will a very cool charger!
