They have Soshine (700mAh), Coolook (700 mAh) and Powerlion (650mAh). I guess Soshine is the most know brand of the three (to me), so I ordered some. Charger is about $8.
There is a thread by Ouchyfoot on Coolook AAs.
Would be cool if there were more tests for LiFePO4s - capacity, discharge etc. (AA, 18650, 26650).
