I just purchased Coach K's zone offense video and I really liked it. What he does is tries to teach more in concepts and generalities of how to play against a zone whithin his motion. He is of the belief, we all spend so much time practicing our man stuff, why let someone take you out of it by zoning you. He believes in learning how to beat a zone (ball reversals, spacing, odd vs even / even vs odd, screening the zone with shallow cuts, bigs starting deep "below" the zone and flashing into space, dribbling at gaps to bring the zone to you and then passing to the next player etc). Personally, I would recommend it for all levels of player. It is more of teaching your kids how to play than running set plays.
