So I finally got a 50D and was not so much dissapointed, but suprised that the remote control wasn't a feature. Not the end of the world, I moved on to finding a battery grip, I happened to find a Ronkinon grip with a remote sensor built in and comes with the remote and got it for 28 bucks on ebay to boot! This has just been my lucky week. I got a 50D with 8k actuations, with 7 batteries, 6-2gig Sandisk Extreme, and 2 4gig Extreme III CF cards for 575 shipped as well. Anyways out of all the remote posts for the 40/50d that I looked at I never saw a grip with an ir sensor (on the front and back) as an option so I just wanted to share.
