I'm trying to find a used keyboard in Bangalore. Casio CTK-230, CTK-240 or CTK-1100. Basically the cheapest possible set of keys with full sized keys on the instrument. Don't care about the sound because I'll upgrade later to a Yamaha PSR series after an year or two once I finish learning on this thing.

Any idea how much it will cost ? And does anyone here have one for sale ?
