Aaron,

Here is the one I made up while bored one afternoon many many years ago...

Take a broken, cheap a$$ piece of college furniture, cut it into a bunch of pieces on a table saw. Find 2 thread tensioners at a craft store, an old arrow for a smooth thread guide, a handful of sheet rock screws, 1/4" bolts, and a few wing nuts... total cost = $10, total time involved, 2 hrs.
