Hi Mario,

My advice is that BEFORE you go out and buy ANY acoustic piano, read "The Piano Book", by Larry Fine.
http://www.pianobook.com/

This truly is "the" DEFINITIVE book to buying a new or used acoustic piano and well WORTH your investment. It covers ALL the ends and outs of piano buying, and includes a comprehensive section which breaks down each major piano manufacter's piano production, thru the years, and recommends which year/model(s) were the best/worst vintage years.

Good luck and keep us posted.
