Best way to get "good stuff" is to hang out near the lab and make friends with the graduate student who work in it. Grad students are always scarfing up things - back in der olden days, we used to latch onto any piece of equipment that was left in a hallway...
Another idea is to go dumpster diving outside outside of a certain Lockhead Bldg. in SoCal.
the dumpsters are in back....
Then there is the Boeing store...
