hi im new to this, i recently purchased a sony camcorder(dcr pc 106) and i was wanting to buy a spare battery for my camcorder and i havent decided if i should get an original sony battery or a third party one. The price between the two is quite a big jump! has anyone bought a third party one and found any problems with it? if i buy a third party one surely i can charge it up using the docking station/ ac adapter i got with my camcorder. I was told that by a sales person in high street retail store that third party batterys will most definetly do internal damage to your camcorder, so he suggested that i should go for the sony battery, which i found out to be quite expensive! thanks for any help.
