I get that way sometimes...that's why whenever I spend money on myself for archery gear I always clear it with my wife first...and then try and make sure she gets something of equal value, if not then, then the next time we have spare cash.
So she's got a bunch of different hand drums, flutes and instruments...and I've got a bow, broadheads, basically everything I need. And unless I absolutely need it for what I do, I don't buy it. A little guilt keeps me from accumulating too much stuff, and helps me remember this sport is about the shooter, and not the gear.
