Canon Digital Minidv Camcorder Better Than Expected Need A Remote Control For A Canon Digital Rebel SLR Camera. Too Many, Which Should I Get? Is Generic Ok?

Need a remote control for a Canon Digital Rebel SLR Camera. Too many, which should I get? Is generic ok? - canon digital minidv camcorder better than expected

I bought a remote control for my friend, Digital SLR Canon Rebel. Search online, I came across several models from Canon, and generic remotes that can be used for different brands of digital cameras? If someone comes, the camera, SLR or have known better, please give me an idea of what I get. I am a developer, to buy off eBay, it is cheaper in general. Thank you.
