I have reservation on the so-call gray-market pianos. 钱串儿's Yamaha UX3 is one of them. There has been a controversy on if it suits the climate of North America or not. In the early year of Yamaha’s invasion to the America piano market, lots of Yamaha pianos were recalled due to seasoning problems. After that lesson, Yamaha has been seasoning the wood differently for different regions. There are three of them: North America, Europe and Asia. All the gray-market pianos (including Kawais) were seasoned for the Asian market. Yamaha tells that those pianos are definitely not suitable for this climate, while the dealers of the gray-market pianos tell you otherwise. Some dealers even say that it depends on which region you are in, e.g. in the humid summer Texas is a “yes”, while in the dry winter NY is a “no”. I have read Yamaha’s explanation, and believe it is true, though I can not tell how much it exaggerates the result of it. (see http://www.yamaha.com/yamahavgn/CDA/ContentDetail/Text_WithCatMenu_XC.html?CNTID=12175&CTID=410010.) After all, Yamaha does have heavy interests in there. So do all the dealers. Personal experience: I have seen one of the gray-market Yamaha grand turned into very bad shape. However, I can not draw conclusion on just one unit. To all of you interested in those pianos, I do not have a yes or no for you, but I think need to be aware of that it is a risk you are taking.
A few more points: 1) Although you think that you are getting a great deal, those are high profit margin item. Negotiate hard. 2) Although you see Yamaha or Kawai names on the pianos, it does not mean they necessarily have the parts of Yamaha or Kawai. I have seen off-brand hammers and other parts replaced in those pianos. 3) In some ads, you will see the word “manufactory” is used, most will be lead to believe it refers to the original makers of them. No, it refers the manufactory that refurbishes the piano before shipping to the US.
