I will not speak of the quality of the product. I think everything has been said.
It is clear that it is not wrong by buying 800MK2.
I am a beginner, but nevertheless I could test the CDJ-200 and Vestax CDX-05 for 2 weeks and indeed the CDJ-800MK2 stands out quite clearly.

I just bounce off a black dot (redundant on all Pioneer DJ Products): The price. Ok so everyone says "Pioneer is normal, it's expensive but the price of quality." I'm sorry but this argument is not acceptable! Pioneer Car is expensive FRANCE (or Europe).
I bought my two turntables in the U.S. for $ 620 each ($ 588 without tax). If we convert the price in France in $, it is close to 2 times that. The product is the same, quality is the same. Here again Pioneer has overall more expensive than other brands but the difference is not as severe as in France. In addition to the huge gap RELATED tax Francaise, France Pioneer does not add a little bit in the balance?

However the product is great. I just had quiquonque council to find a way to buy abroad has his turntables. With the Internet, it's getting easier and easier.

So: 9 for the product, 9 for the price the United States, two for the price in France.
So I have put a double note:
CDJ-800MK2 in France: 5
CDJ-800MK2 United States: 9
(If we forget the price: around 9 ... And when I more control plate, probably 9.5)
