There seems to be a fair bit of talk about aftermarket batteries.

But what about aftermarket chargers? I had some gear stolen, and the battery charger was one of those items.

Now I'm faced with the option of buying an aftermarket item for 50-80 dollars.
Or a genuine Canon item for 100-130 (actual Canon endorsed spares site is the dearest)

I can also get a charger that looks real, but is from Hong Kong, for around 50.

My dilemma is that I don't want to pick up a charger that's going to burn through on the charge and do fast charges or something that will kill my battery. Or am I simply worrying too much?

Thanks
