I was out camping recently,a friend had a Vello he lent me...his was the wired version, and it worked great for doing some time lapse shots.
I just bought the wireless version, and tested it out last weekend....it is about $99 no tax at amazon.com:

Pretty neat, you can use for intervals, you can set exposure times, etc.
Give it a look, I've been happy with it so far.
My needs right now (I've posted the questions on the gear talk -> EOS Bodies for Stills thread)...is what setting on the camera itself are best to use...?
Do you use one of the smaller RAWs?
Manual or auto....especially if you're time lapse takes you from daylight all the way into dark?
What interval? If shooting for 24fps video...is a multiple of 6-12 or 24 best to use?
