Pat,
It depends upon what you're looking for out of this piano. I own the Yamaha model you're looking at (for a little over a year now) and I've been generally satisfied with it although it has needed a couple voicings to soften the tone. It's in a really "live" room with hardwood floors that really accentuates any harshness.
I went into my purchase with the understanding that this is more of a learning instrument rather than my "dream" piano... this I imagine I will reward myself when I become more accomplished and (more importantly) acquire some disposable income! My desire was to become a better pianist without getting a second mortgage, so it was vitally important to get something that had good touch for a reasonable price, if such a thing existed. For me this was the Yamaha. The tone is a little thin compared to the European brands, but they do have a very good feel IMO--my bigger concern--and it has helped my playing very much. For this reason alone I have loved every minute of it and I really think it's a fine instrument to learn on.
Now, if I had more money to spend I would have strongly considered the more expensive Petrof upright. Yes, they may require more prep as a result of being less mass-manufactured than the Yamaha, but you will have a piano that (again, IMO) has a warmer tone which will age much more gracefully than my little Yamaha. From the Petrof owners I've talked to, they have been very impressed with the quality of these instruments.
For what it's worth!
