If I were a beginning golfer, I would probably look to buy a used set either off a friend or a retailer. I know someone like Play It Again Sports probably offers starter sets that they build from the random stuff they get in.
To start off you don't need every club available, just the basics like putter, 3,5,7,9 and maybe pw.
That being said, 100 isn't too bad but you're still going to need to shell out some money for a putter and a bag.
