Apparently it's expensive and rare. From the Wikipedia page: "In 2002, the price was US$94 per kilogram. The recent changes in demand and supply have resulted in high and fluctuating prices of indium, which from 2006 to 2009 ranged from US$382/kg to US$918/kg. It has been estimated that there are fewer than 20 years left of indium supplies, based on current rates of extraction, demonstrating the need for additional recycling.[37]"
