Wow, i thought i'd feel foolish to have so many, but you guys have real problems! From small to large with rating out of 10 based on amount of regular use:

Olympus xa - 3
Konica Auto S2 - 6 (comes to work with me every day)
Nikon n75 (1st camera, gift to a girlfriend, thrown back at my head as we broke up 2 months later, i owe her a lot!) - 2
Nikon f100 - 4
Voigtlander Perkeo II - 8 (love it for so many reasons)
Rolleiflex 2.8F - my dad's from 1968, moved me to medium format, my most special camera, perhaps too precious - 5
Hasselblad 501cm - medium format workhorse for most serious work - 7
Plaubel Makina 67 - early days with this camera, no rating yet
Chamonix 4x5 - if i were all alone in this world, i could be happy wandering it slowly with only this camera - 5

Yes, i'm very lucky. They're my only expensive habit. And my wife will kill me if i buy any more.

Canon Rebel T3i - my wife forced me, i swear! - 5
