Wanted to report on this! Woohoooo! I got my grip in! Went the CANON route.
There are a couple benefits I am just now realizing. When it is attached to my Flash bracket that swivels... the flash bracket actually feels right now! Before, it was awkward, cause if you had the bracket on the right of the camera so you could flip it up top when shooting portraits, it was real awkward to hold when the bracket was in landscape position. This way, since the bracket mounts so low on the camera, I can hold the camera in portrait or landscape and it will feel totally right! Yes! Now I can actually use the bracket and it feels fine!
Another thing... I've never really minded shooting with my hands twisted shooting portraits... however, I am probably going to shoot a huge basketball tournament...which a lot of shots will be vertical. Now that I will be shooting a lot of vertical shots, this feature will actually come into play!
Also, I am super excited that the old battery door fits inside the new battery grip...this way I won't lose it.
Overall, super happy with my purchase! This was one of the first "Fun" things I have bought (that I couldn't completely justify buying) and I am glad to have made the purchase.
Thanks for all your advice TPF people! (i almost said TPF'ers but that sounded funny)
