Goodguys had a sunbeam one on special for about $60-70 a few weeks ago. In my opinion, get one with a good number of trays (4 absolute minimum) with the lowest temperature possible. You dont want to cook the meat, only dry it.

Pretty much anything will work you will just have to experiment a few times to get spacing and things right. In a pinch, make metal hooks out of wire, put your oven tray on the top rack and something on the bottom of the oven to catch drips then hang your meat on the hooks off the top rack. Crack the oven door open slightly and set it for around 50-60 degrees depending on the oven (fan forced only).
