I appreciate all of the advice I received on this subject. I looked at the options out there and the pricing and found a 70-200 f4 IS new for about $970. I just couldn't break the $1000 mark just yet. In looking for the lens, I just couldn't see getting the non-IS version for only $250 to $300 less. I think the IS will well make up that difference to me in future pictures. I chose the f4 over the f2.8 for two reasons 1) I found it for under $1000 and seemingly from a reputable dealer. Hopefully that is the case when it arrives here Thursday. 2) I decided that at this point in time I will not have a whole lot of indoor shooting without lighting assistance, so I think the f4 should do the trick. The f2.8 was very tempting, but I believe in IS and I know it has saved many of my shots on previous lenses. Once the lens arrives and this darn snow melts, I will try to post some shots for critique. Thanks everyone again for their input.
