There are junkyards in SecondLife where you can pick up cool stuff for a buck or two. Not sure how you find them though.
Another good place to pick up stuff is supposedly called "Yadni's Yard" which can be found by searching under the Places tab.
and we're supposed to check out the den of randomosity in the Baku region, coordinates 170 by 173
there's supposedly something called Learn Island - with educational stuff (I'm a prof ok - educational stuff is exciting)
but so are comics and here's a SL comic - http://www.plywoodcomic.com/strip1.htm
