When you start you probrably wont have your own clubs and wont want to commit to a full 18 hole game. we recomende you start by borrowing a pair of clubs from a driving range or if you want to play on a course, play a 9 hole, par 3 short game with borrowed clubs
When buying a set of clubs i recomend just purchasing a set of irons and a putter and not a driver or wood as you still probrably wont want to play a full 18 hole and you are still getting into the game and spending more might not be wise. For a brand, it doesnt matter, find a cheaper pair you like the look of and then figure out what shaft you want, steel or graphite.
When you have established your enjoyment for the game we recomend becoming a club member as it can save you money on playing regularly. We say you should become a member at the club you have been playing recently. It may also give you rewards bepending on the club you join as a side bonus!
