The one from Strike looks to be a really good one, and is similar to one that I have.
Another one that bears a look is the Triton series.
However, my current fave iw my Hyperion 6061 - it runs on either AC or 12vDC and is pretty darned smart. Handles LiPo and LiFePO4 as well as NiCd, MiMH, SLA, and others.
Cheers,
