I have so many to choose from that this is a tough question! At the moment I am most pleased with the solid cherry 1920s vintage desk I use as my makeup table--bought at an auction for $5.00.
I rarely buy anything new (not counting food of course!) and have also found good new homes for many items. When I moved in the fall I needed to do exactly that for a lot of random tools, furniture and household items, and if I could not sell it I put it at the end of my driveway and listed it as 'Free' on Craigslist.
It was amazing how well this worked.
