I do the same using Ableton Live.

Not much in the way of technique to share, though, I just listen to a freshly purchase stack of crusty vinyl and when something sounds interesting, I sample it. Sometimes I like it enough to work on it right away, while other times I keep it for later. I usually end up processing the files quite heavily (time stretching, granular synthesis, etc.) but once in a while I'll leave a sound or sample as is, because that's just how I like to hear it back.

Also, and I never sample stuff that's recognizable, that's a moot approach, imo, at least for the stuff I do (dark cinematic electronica), I love going for the older and obscure stuff, international records from people no one's ever heard of, 60's stereophonic sci-ci and orchestral recording, basically the stuff you find in the bargain bins at most shops, the crap no one else wants is my gem.
