about 300 now. When i was living with my friend i counted his collection, 2000 and shoe boxes full of Rocksound and Metal Hammer samplers. but most i've seen is at another friends place, his dad had over 4000, i wouldn't be surprised if its 5 1/2 thou by now though (being a psychiatrist he can afford to buy that many, but really, how could he ever listen to all the new stuff he buys?)
