I have been looking hard and they are out there at that price but you have to search for them, so have you tried it yet and happy with the results?

I have tried it out on the last two footy games and very pleased with the results given that its a fast moving sport and being winter the light isnt always the greatest. I played around witht he F stops a bit and found at 2.8 I need to bang on with the focus on the subject to get a good shot. At 4-5.6 I seem to have a I higher hit rate of better shots.
As an example your DoF at 200mm on a focus point 30m away is approx 2.5m at f/2.8, 3.8m at f/4 and 5m at f/5.6
