I did see your post down there.  The section on Petrof is too long to copy it here.  However, the review is generally positve and says that Petrof's quality has been improved since the previous editions.

There is a rating on all brands, which might be helpful to you.  I am only listing Petrof and Yamaha here, with the latter as a benchmark.

The author breaks pianos in 5 groups, and each brand is being rated in 5 categories:

 

The five groups are:

1.           Highest quality performance pianos;

2.                  High-performance pianos;

3.                  Better quality consumer-grade pianos;

4.                  Medium quality consumer-grade pianos;

5.                  Economy pianos.

Petrof is group 2, while Yamaha C series is in group 3.

 

Then, the five quality categories (with 5 stars as highest rating) are:

1.            Performance:  Pretrof  4 ½  vs. Yamaha 4 stars;

2.            Confidence:   P. 4 ½ vs. Y. 4 stars;

3.            Quality Control:   P. 3 ½ vs. Y. 5 stars;

4.            Warranty:   P. 3 ½ vs. Y. 5 stars;

5.            Information:   P. 4 vs. Y 5 stars.

 

To you, No. 4 & 5 are irrelevant.  This is my thoughts on why your teacher and her technicians have such a bad impression on Petrof:  They did have negative experiences with Petrof when they were in Russia, when both Russia and Czechoslovakia were under communist regions, then, there was not incentive for the makers to improve the quality.  Once they are imported to the West, they have to compete to survive, so that the quality has been improved in the last decades.
