For the irons, it may sounds stupid but I was impressed by the Starters Plus. Almost the same as the Starters but with a much lower meter speed (cut by half)! ...and for 50 credits for the whole set you can't go wrong.
Apparently, the Spider is terrible for the precision, but forgiveness and speed seems OK. I would wait til he gets to Pro and buy the Daytona for 750cr. If it's really too much, the Ping Anser (400cr) is pretty good too as I used it for a while.
But 1200cr is not a lot. Eventually he will have to fork out a bit more. The Daytona + a good driver (ex. the G10-10.5) + the Starter Plus = more or less 1500cr.
Add maybe 1 or 2 good wedges (52w or 64w) and you're around 2000cr. But for the "price-of-5-cups-at-Starbucks" that you put in credits instead, believe me the game is a lot more enjoyable.
