I understand that getting a piano with light action won't solve my tendonitis problems completely, but my current piano (a pearl river upright) has pretty heavy action. Even though my tendonitis was caused by tennis and typing, playing piano has been imposible for me as well and i've been resting for the past two months (i've been playing for a year). Once I get back i'm hoping i won't get it again. The most my parents are willing to spend is 4-5 thousand. To clarify, I'm looking for both new and used pianos. So which pianos in general have light action? Thanks for your help. -Amit
