Over at Rekkerd.org is a pretty cool sample pack available for freesies.  Mostly intended for rhythms/percussions the recordings could certainly be used for that and much more:

For Rekkerd Sound Recordings Vol. 2 I found a number of interesting objects to hit, drop, slide, slam, press, etc. After a good amount of editing the pack ended up containing 90 samples. Various noises produced by light switches, fans, drawers, and lots more included.

The samples are in 24-bit/44kHz WAV format. Plenty of background noise is included, and those with a good ear might spot one of my kids in some of the recordings. 100% high quality lo-fi!

Rekkerd.org is a pretty cool place to keep an eye on for sample packs and plugins anyway, so head on over.
