Dude, I'm fairly sure you can ask your local telephone wiring chap to give you one for some chai-pani types. (assuming your place has DSL connectivity, but why would you need the splitter if it didn't..?)
BSNL/MTNL/Airtel keep thousands of these things in stock and their technicians always carry a few around. The 100+ prices on Ebay are a rip-off IMHO...
