I had a grip for my XT back in the day and loved it. I want to get a grip for my somewhat newly acquired 60D. I love this camera but want the added functionality that I enjoyed with the gripped XT. Should I get the OEM version or a 3rd party? If 3rd party is the recommended route, which brand is most reliable? I don't mind paying $139 for OEM over $50 or so for 3rd party if it lasts as long as I need it to and it functions correctly. Thanks in advance for your thoughts and advice.
