I've got the Nikon 55-200VR (Vibration Reduction) which has Image Stabilisation. I use it on my D40SLR.
It's absolutely superb. Highly recommended. Just one thing though - if it's on a tripod apparently you need to switch the VR function off. No idea about Canons though.
I buy cameras made by camera companies, not photocopier manufacturers.
(Joke!! Before all the Canon fanbois jump down my throat!)
Just wish my 55-200VR would work on my Nikon F90X film SLRs, but can't have it all I guess.
