Tempering machines Australia

Hi , I work for a charity and have just started a hand made chocolate range to be included in our Cottage Industry. The intrest in our chocolates is great but the demand has made ne realize that we need to get a triple chocolate temperer does anyone know where we could put purchase one at cost?? My organization is a charity so cost is important .. We currently have Mol'd art tempering bowl which is amazing but the triple one would make our production so much more efficient !
