I stay away from the sampling records thing.

As for sounds, what I tend to do mostly to keep the volume down , is find a kit I like, either mine or a friends, take it to a decent room and record them and me playing hits at various velocities as well as fills and patterns. I just run to DAT cutting down down some of the Studio cost.

Bring the DAT or CD home and either chop it up in a Sampler or on my PC.

To get it right it really takes about 6 months minimum to get one kit library organized and programmed correctly for a wide range of uses.
It also gives you a custom library. Ok it is not the cheapest way but it works and doesn't need to be done in a super high cost studio to be effective for home studio projects.
