I agree in general, bubba, but in one point I have a different view (pointed out by crossing out one word):
bubbadork: At low levels you get to buy more good stuff than you can use.
That said, the good stuff comes later, it's worthwhile to wait.
My favourite line is "Wait until you don't stand the wait any more". You should also know that the courses become longer for Pros (your next advancement) and Masters. The latter may require extra consideration for strong clubs.
By playing one or two strokeplay games every day(!) you may win one tier per day until in the mid 50 levels, and then you are close to level 59 where the G20s are released.
Whether you want to buy something in between depends on your purse and on your eagerness. A budget solution might be to get the lvl 47 Rapture 3WD(!) as a driver replacement, the whole Rapture set is a good choice as are some other sets (G15 etc).
My recommendation for your next buy would be two decent short wedges, lvl 29 Clevelands or better (lvl 42 Pings are budget-priced). They will certainly improve your short game tremendously!
