I have had a Petrof vertical for the past 10 years and have been most pleased with it. You will also note that Weinbach is presented in secondary order to the Petrof and is described as being an international collaboration of design and manufacturing from Czech, US, Germany, and China while the Petrof is not described in this manner. Petrof's grand piano sizes are 5'3', 5'8', 6'4' and all the way up to 9'. I am surprised that you found a 6'4' Weinbach, it looks like the Weinbach grand pianos are issued at different sizes from the Petrof - 5'0', 5'5' and 6'0'. The string material is also different and so too is the rim. Petrof is a superior product line: the keyboard is made of solid spruce while in the Weinbach it is made of veneers. Check out the Geneva International's website (US distributer for Petrof, Weinbach, and Nordiska pianos) for the specifications of the different Petrof and Weinbach models.

My Weinbach is black walnut, and the cabinetry is absolutely gorgeous and cost no more than ebony. An advantage of both Weinbachs and Petrofs is that they do not charge more for finishes other than ebony. Of course, the Petrof's action, being magnetic, was lighter and more responsive than the Weinbachs'. I compared a Petrof with MAA with three Weinbachs the same size, and as each instrument is, of course different, I found the sound of two of the three Weinbachs preferable to that of the Petrof. The price you quote was similar to the deal I got in Chicago last month. My Weinbach has Renner parts mounted on a Petrof frame. Weinbach has a smaller selection of sizes and models, and the magnetic accelerated action is available only in the Petrof. The materials are supposed to be identical, and the pianos are until now manufactured in the same plant. I also noticed that the Weinbach has a so-so decal on the fallboard whereas the Petrof has the name engraved (really cool). The dealer stated that the pianos are identical except that the Petrof has glossy paint on the plate and has green felt rather than red. I just chose between a 6' 4' Petrof and Weinbach.
