Lets see
Car audio equip about 2 years ago spent $1200 on HU, amp, and comp fronts (no subs)
Paintball (Marker+equip is about $1000 I spent in the past 6 months on it)
Computer+Dell 2407 ($2500 on last spring and still a great system)
Pioneer Kuro 5080 HDTV ($2500 this spring)
Cutlery ($175 on 2 knives so far, both Global knives one is a 7 inch santoku the other is a 4 inch pearing)
Home audio is going to be a future purchase, but will include it because I am looking at ~$3k speakers and about $5k total but am going to wait to move to a bigger place for it (no where NEAR the space I would need to make it sound good)
DSLR+Lenses I am going to buy in the next month or so and spend $1500 or so
Surefire Aviator $200 and everybody goes "why would you spend that much on a FLASHLIGHT!?!?!?!?!" Then the first time its needed (or want to show it off in the night) they all go "WOW that thing is AWESOME, I want one." This past weekend was visiting relatives and my uncle got out his massive 3d/4d (dont know which) Maglite and was playing with it. I pull out my Surefire and about the only thing he could come up with as to how his was better is that he could use his as a club if need be. He also said "Well you have fresher batteries thats for sure" when we put them up on the wall and mine hosed his completely

. Thank you Surefire.
Edit: almost forgot skydiving $200 for a tandom jump, and a friend and I will be getting certified after college ($2000), and getting our own equipment ($2000 for some used stuff).
