i spent 6 months over a winter/spring going to Golf-Tec, the price was similar to what you're finding. those consistent lessons are the single biggest thing that improved my golf game, as i dropped 5 points off my hcp over the next year. i would not describe it as robotic, rather they have a definite method and my coach worked with me on a preferred swing. now, those fundamentals of the swing are exactly where i needed to get better and where the payoff was to be found for me. and i'm not a swing-thought guy, so the visual images of pros in the videos that i could compare to videos of my swing, plus finding the feel of a better swing through the use of various aids really paid off for me.
the same number of lessons from my course pro would have been less expensive. but they wouldn't have taken place during the winter, they wouldn't have included the technology and two-direction video of my swing, and they wouldn't have included sim bay practice time. if it's in your budget, i think you'll find value.
