Remote Shutter Release

[Beanie]

I know they have these for SLRs - do they make them for a DSLR? It would be snazzy to have one that I can use on my Rebel and Digital Rebel both, but right now the digital is my priority as I can always delete something instead of wasting film... but if they only make 'em for the 35mm then I guess that's what I'll get!

Suggestions? I poked around Ritz Camera but wasn't really sure what I was looking for so I gave up, LOL. (Also it's dangerous for me to browse there!) I'd really like one that's a wireless remote if possible...
