I don't really have numerical limits here honestly. It depends on a) can I afford it and b) how much better is it than what I currently have. Standard retail prices for equipment are a little high in my mind, so I'm always looking for some discount and/or buying used. I'm also weird in that I think some clubs are more worth dropping cash on than others.
The most I've ever spent is:
Driver $400
Fairway Woods $150 (each)
Hybrids $50 (each)
Iron set $1000
Wedge $75
Putter $200
DZ Balls $20-30
Average round $40-60
