Advice on developing a superior golf swing

[GolferxJames]

Hey... James Here... I've been golfing now for a little over a year and I think my game is at least half-way decent.. however, the last two games which I played with a couple acquaintances at the local course I was totally destroyed! These were two individuals who were only playing for about as long as I have but they both had incredibly superior swings which I can't seem for the life of me to duplicate.. and what's weird is when I found out they've only been playing as long as I had, I asked them where they learned to swing like that, and BOTH of them actually recommended to me an online golf swing course type thing from http://www.golfswing.pcti-system.com .. which I'm probably going to get. However, before I did I jus wanted to find out if anyone else here is familiar with it or has tried it and what kind of results they achieved from it? I think im going to go for it, but I just wanted some 3rd and 4th opinions. Any advice / comments / suggestions would be appreciated.. thanks!
