Apparently Mugen has replaced the dead Lion site where I used to buy batteries. Wish I had known that before I bought my Seidio one. The Mugen 1500mah was half the price with free shipping when I checked it out.
I wouldn't mind the added bulk of the bigger extended sizes. But I couldn't deal with the uneven back and rocking action when I type.
