has anyone experience (good or bad) with non Canon batteries ??
I've seen a few advertised (here and here for example) for almost a third of the Canon's cost.
Canon seems to have a big mark up on their batts -- Sony's 970 batteries are much cheaper.
Has anyone ever tried the off brands ??
interested in learning if they work reliably, if their dimensional tolerances are slack -- thereby making it a chore to extract them from the Canon's battery anus, if they fail prematurely, or if anyones heard of them exploding etc etc ??
