La Crosse Technology Charger: the latest model?

Hi, which is the latest La Crosse Technology BC-900 AlphaPower Charger model for AA Ni-MH batteries?
Do you know an online store with a good price?

After the BC-900, they introduced the BC-9009, and now the BC-1000 is the latest, greatest, with some circuitry to avoid meltdowns.

Good explanation of the differences in NLee’s review here.
