John, Suggest you buy a used Silca off ebay and put a rebuild kit into it. Sometimes you can get them for $30. Make sure that you get one of the earlier ones that does NOT have the 3 legged base. All the rebuild parts are available! After that it will be good for another 20 years. It's the same kind of enjoyment you get from putting a long neglected bike back on the road. But cheeper.
