humidity help?

Does anyone have any good ideas on how to cut down on humidity in a curing chamber?  Up here in Daly City the RHG is about 85%.  I would like to avoid buying a dehumidifier now.  My chamber is a full size fridge with a automatic temperature control.  I keep it around 50 degrees so it cycle on more, but the air it takes in is too humid anyway.  I thought of cutting a hole in the fridge and setting up an intake fan like Jamie's set up but then I would only be bringing in more humid air.  The only solution maybe to just get a dehumidifier with a digital control, but these seem so expensive  Any suggestions would be great.  In the summer when the temp is higher outside it wont be such a problem, but now it is keeping the RH at 80-85%
