You need to decide if you are more likely to be a serious student of the game, or a golf marketers dream.
If you are a serious student of the game, get fitted with quality clubs and take lessons. Spend more money on lessons than equipment. And practice.
If you are a golf marketers dream, buy the set of clubs that is getting the most current media attention. When you start missing putts, go out a buy a new putter - or two. You can never have enough putters. When you hook or slice your drive, run out and buy the latest giant oversized graphite driver. Make sure to always get the latest and greatest - and keep your gold card handy. Lean about COR, MOI, CG, UTW, ICT, RE*AX and other "important' terms.
Good luck.
