Well, I don't want to spend money I don't need to spend, but I am having more fun with this hobby than I've had in a long, long time. I plan on sticking with it, and half of me wants to get (well more than half) a nice charger 'cause I LOVE TECHNOLOGY!!!

So it's OK to get something like this and charge all my batteries using it:?

I wasn't sure if I could trust doing that for the majority of my charging.
