Okay 95% of you, have seen "Tin Cup" and what's her name showing up for her golf lesson with every gadget under the sun, plus the golf watch to help improve her game.  Well I'm about at that point of trying anything to get my game on track.  If I had the time to take lessons I would but my golf outings are very limited.  I have 2 small kids, so I'm just grateful to get the chance to play when I can.  I can however find some time to go in the backyard and swing the club a few times. 

What is the magic training aid out there, that has shown the most improvement to your game?  I've looked at the Medicus, impact bag, speed stick, videos, etc..., you name it, .  I'm just leary of all the the different aids but not one that really stands out as the go to for game improvement.   

I'm not looking to be a scratch player but one that can at least have an enjoyable time on the course and not hold up play.  I purchased a new set of irons last year (Callaway X-20).  Thinking the new improvements to technology would do something.  Honestly, I'm not seeing a big difference from my old irons (TA 845s).  So, before I decide to take up bowling.  I'm interested in hearing what some of you have found as helpful resources to improve your game on a budget.
