Have been looking at switching over to rechargeable batteries and getting a solar recharger. Figured this would be a good place to ask for info.

Any recommendations for or against?

I was looking at the Goal Zero Nomad 7M and need to be able to at least recharge AA, AAA, and CR123. (Seems like most items take CR123's these days.)

Are some rechargeable batteries better than others?

Thanks in advance...
