Just today, I found a fantastic dresser for $35. It's not one of those cheap veneer jobs either; it's old school solid wood and will probably out last me. =D
There actually are diamonds among the junk on Craigslist. I also found: a piano with bench for $50, a free piece of vinyl fencing (worth about $60), dirt cheap firewood & a Sega Genesis with a dozen games for $35 (nostalgia thrown in free).
If you need anything that you can pick up yourself, check it out.
