The case for maintaining your current piano.

     You should invest in maintaining your piano because:
1) Unless a new piano is a Steinway it was made overseas.  With cars and a few other things there can be made a case that the foreign made product is better than the American product.  This is not the case with pianos.  The best foreign brand new is no match in quality of materials or workmanship to a good american brand such as Baldwin or Mason and Hamlin that has been rebuilt by a quality rebuilder. 
2)  A quality complete rebuild could cost 22 to 24 thousand dollars.  A complete rebuild means new strings, pins, pinblock and with the action all new moving parts such as hammers, wipens, shanks, felts and leather parts, and a complete refinish.  When this is done the piano is like it came from the factory.  A new Steinway medium sized grand might cost 95 or 100 thousand dollars.  You tell me which is cheaper.  Even if a complete rebuild is not in the budget a couple of thousand in some regulation and repair could greatly improve a great american brand making it again a joy to play.
3) A great American brand of piano was not designed to be thrown away like an electronic instrument.  I have worked on many 100 year old pianos but never even a 50 year old electric piano except for a Fender Rhodes which was  designed with a parts that can be replaced or repaired.  If your piano has a family history it can be preserved.
