I am probably going to get the 70-200 f4, ordering tonight. I had wanted the IS version, but I won't be working until mid September. I will only use the lens outdoors for soccer for a while and Jon recommended I get the 1.4x extender that works well with the 70-200 if I need the further reach. I may still go ebay for it. Don't know. I can't wait for the triple rebates, but if they are as good as last year, I may just buy everything I need and hope I earn enough in the fall to pay for it all. I will be substitute teaching 3 days a week at one school and 2 days at another, so it's pretty much full time. I won't be on teh forum until the evenings and early morning now. But I can afford good glass and that's important.
