Hm, Ive been researching the remotes for the 350D, have you got yours yet Mike?
The only thing I dont like about the IR ones (RC-1, RC-5) is that you have to be in front of the camera to use them, and they dont have/support half-shutter to get auto focus. I might look into getting a wired remote (RS-60E3) for the moment, and you can tell me what the RC-1 is like when you get it.
