I'm thinking about buying a battery grip for my Canon XTi. I looked at the Canon model and the Opteka one as well. The Opteka sell for about $100.00 less then the Canon. Amazon sells one via 47th Street photo with batterys for about $80.00. I have 2 of the batteys that they sell and they last longer the the Canon battery. I was wondering if anyone has any exoerence with the Canon or Opteka and would be wiling to share there advice on them. I have read review on both and they are mixed both good and bad. I'm not sure that the Canon is worth the extra money so I would like to find out what you folks think. Thanks in advance for the replys.
