Ah - Matt!!! You hit on the two sure-fire ways to end this sort of addiction... bankrupcy and actually fixing/restoring stuff. This second one I find especially useful - it got me out of the hi-fi jones several years ago - I built my own gear and modded vintage JBL - this cured me of listening to all the experts with their latest and greatest...
I still struggle, but then I've not yet migrated to full fledged camera repair... more along the edges still. Once I'm there, once I've torn down a SLR lens, repaired a rim-set shutter, replaced a bellows...
But meanwhile: I lack an interchangeable lens medium format camera and the two/three necessary lenses for it...
