Hi Bboseley,
First, separate all the stuff you
want from all the stuff you actually
need. Figure that even if you bought higher end Sidi shoes (Genius4) for $140-200, this is a one-time cost you can amortize over many years (5-10+) if you take care of 'em and don't walk all over the place in them. Green fees? Balls? All the time you could have spent doing something else? (Riding?) Let's not even go there...
The fitness/good feeling aspect is enough to counterbalance all else - have a great time!
