anyone using 3rd party battery for macBook?

[viodea]

My macBook battery is dying and out of warranty.
I need to find a replacement but the Apple battery is really expensive.
Is there any reliable 3rd party battery out there?
If none of the 3rd party is reliable, I would rather get the expensive OEM.

I wouldn't trust a cheap third-party battery in my MB, go with the OEM.
