OK....I will be the first......200+ isn't even high enough.
When I met my wife, and we moved in together, I had counted about 325.
We moved to where we are now, and I counted them when I unpacked, and put them all into a simple spread sheet to keep track of them.....the collection had ballooned to almost 500 in 2 short years.
So....I tried to thin the stash a bit, sold some on ebay, etc, and got the collection down to about 475, and vowed not to go over the 500 mark. Well, now almost 18 months later, I have stopped entering them into the spread sheet (cause lets face it, it was getting depressing), and at that time (about 6 months ago) it was at 525, and is most likely easily surpassed 550 by now.
However.......I know guys that have 6-7 times that amount. One local guy here has about 3500, and one of the guys that go to the Moncton Club meeting, stopped counting about 3 yrs ago when he hit 3000, and he figures he has easily surpassed 4000 (judging by the amount he buys from me, I believe him), mostly car kits, and as he usually buys the new kits in multiples of either 2 or 4.
