I'm the same way! I thought I was the only one with this problem. I feel so validated to be amongst like-minders.

I have a tiny apt. in Brooklyn, and I recently counted and realized that I somehow have acquired 14! The thing that's kept me going back to the well is not so much specific genre, or brand or model or comps. It's been good deals! I can't help myself whenever I see one.

None of it's amazing, but I have a few nice ones:

80s Schwinn Traveler.
70s Fuji Monterey
70s Nishiki Mixte
Panasonic 500 Ladies's frame
Rusty 70s Raleigh Supercourse
70s Raleigh Grand Prix converted to fixed
70s Miyata 210 (Hi-Ten)
Nishiki Olympic
80s Univega Grand Tourer
80s Univega ...? w/ full Shimano 600 + brifters
80s Miyata Three-Ten (double-butted CroMoly/Mangalight fork)
80s Centurion Elite GT w/ original Mountech comps.
70s Raleigh Competition w/Campy + Suntour Superbe brakes
And the latest, greatest find ever: Trek Élance 400 all completely original in near-new condition. It looks like it was purchased by the original owner for the purpose of going on one tour (Tour de Coors), and never used after that. Even the Matrix tires look barely used, and the Matrix anodized rims are totally unscathed. I bought it for 10 bucks!

I actually think that I'll be able to make a decent profit off of the bunch, but in the meantime, I've lent them out to all corners of friends of mine, and I have also resorted to locking them in scattered spots throughout the neighborhood, so as to avoid telling my lady. We actually walk by them at times, and I sneak quick looks to make sure they're not vandalized w/o tipping her off.

I hope to winnow the group down to about 4/5 at the most within a few weeks. My home has become horribly infested with all things bicycle. But I can't bear to just sell to any people, and I keep trying to pass them on to good friends.

But what a therapeutic pastime.
