Musical Instrument - Ship to KTM

Need some suggestions, if someone had similar experience.. I need to send one Digital Piano to Nepal. IT's about 35 Kg, dimensions something like 5 ft * 2 ft * 1 ft....What are my options ? Has anyone bought here and travelled, any idea how much they would charge at the airport.. ?...is it a better idea to just ship through FedEx or smthing...? Any thoughts appreciated.
