If it is the Canon 70-200 mm f/2.8 lens, it's a very good lens. I have NEVER intentionally bought an IS lens. I rarely use a tripod, and my photos are just fine, thank you. I used my Canon 70-200 mm f/2.8 non IS lens for many years, until it was stolen, and I haven't been able to afford to replace it yet.
Before you buy the "used" lens, check on the price of a new one at B&H or a similar used one, if available, from KEH.
I own the original non-IS. Look at the many reviews, you will find it is one of THE best lens available, bar none. I also used it with extension tubes & flash on my 50D for insects & butterflies before I got a macro lens. Hand-held at 1/250th or faster with a good support technique works very well. Use it with Canon 2X tele for birding in the yard on a tripod, use a mono-pod for airshows. It's definitely not a lite-weight !
