Bosendorfers are very fine instruments, and they are very VERY durable. I highly recomend them for instutional use. I have a Bosendorfer 214 that my parents purchased for me last April. It recieves relentless use for about 4 hrs a day. I have nothing but priase for it's performance. It is an incredible piano with a tone that is unparalleled. Two good friends of mine have Bosendorfers, a 225 and another 214 and they are very happy with their pianos. Also, my teacher has a Bosendorfer 214 in his studio at the univeristy. It is also responding positively to all the use it receives. Before he became a Bosendorfer Artist, he had a Steinway B in the studio that had many problems. It had absolutely no tunning stability, it was terribly out of regulation, and had an unpleasent tone. This school is known as a Steinway school. However, the school is growing to like its Bosendorfers. In their concert hall, they have a NY Steinway, a Hamburg Steinway and........you guessed it, a brand new Bosendorfer 280. And guess what piano gets the star-treatment?
My 2 cents-
