Excuse me but the 75-300 USM
lenses (the 250 euros one) one of the best, if not THE best 75-300 in its pricerange. Ask anyone who uses or used it. Glenn Stewart, Luis Rosa, Ben Pritchard, myself and many others are/were very happy with it. (some of the above use the IS
version, but thats basically the same lens) Ok it is not L glas, and you get what you pay for, but you get a hell of a lot when you buy that one.
EDIT: I now see you might mean that the lower end Sigma 70-300s are no good. if thats the case then you are correct
