Best place to get generic camera batteries?

[FleshLight]

The LI battery to my 4 year old canon s200 is dying out and I don't wanna fork over $40 for an OEM battery. I see a whole bunch of places online that offer generics but I was wondering which one was the best.

i ordered 2 batteries and a replacement charger for my Canon S400 from Sterlingtek awhile back without any problems. worked as advertised and saved abit.
