Is the Billy Goat KD512SD a good lawn vac? - billy goat lawn vac

Looking for a lawn vacuum to suck leaves and grass. This seems to be very successful, with over 1500 CFM. Can anyone comment on the performance?

Moreover, if this is not very good, then what is in this price range it? I need to strive through the grass, but the leaves is a big plus.
