Ha! You beat me on making that recommendation. I have used a BC700 for about two years now, and am very satisfied with it.
I particularly appreciate how each of the four battery slots is separate. Not only does that mean each battery can be doing something different (charging, refreshing, etc.), it also means you can remove and insert different batteries at different times. This is great when some batteries are more (or less) discharged than others.
Also, worth noting that the BC700 supports NiCd and NiMH, in addition to AA and AAA.
