Swim lessons?

I know I have talked to Cronz and Slim about this, but this guy is a Total Immersion coach in MPLS. His masters program doesn't fit my schedule, but this private lessons deal I think would be good to get some drills to ensure that our stroke is most efficient on game day. I was thinking about getting this rolling sometime in the winter, wondering what you guys think about it? Check out his website and let me know what you guys think, if all four of us did it I think it would be about $85/person.
