The Sigmas I have aren't that cheap. Usually the difference between my Sigmas and a comparable Canon is under $100.

Oh, and the Sigmas I have are better than their Canon counterparts biotch.

 

The point about risking your camera is a good one.

I had forgotten this but early in the life of the Nikon D70 there were several reports of aftermarket battery leaks damaging them. And, of course, Nikon denying warranty service because they sent the camera in for service with the non-OEM battery in it (honest but dumb).

Another point is not everyone is honest about mA-hr ratings. Some have been known to exaggerate (though my non-Kenwood battery mentioned above does operate for over 2x the OEM battery's transmit time).

 

The canon grip is a no brainer. So the batteries aren't a go?

 

I personally, wouldn't risk it. I just don't see the point of getting into such an expensive hobby, and skimping on the cheap things which can kill the whole system. A real battery can be had for $45.

 

Alright I understand. Battery grips only require two batteries correct?

 

No, you can use one. They can hold up to two.

 

I might as well have two in there, no? Longer life. Can you charge the whole battery grip as a whole? or do you have to charge each individual battery? Would it be wise to buy another charger?

 

I always keep two batteries in my grip and one in the backpack as a backup. I spent 2+ weeks in Asia taking a lot of pictures and never drained the Sterlingtek batteries any appreciable amount.

You have to take the batteries out to charge them individually.

 

Anyone ever have problems with the Sterlingtek!?

 

No problems with the Sterlingtek.
