There might be those vendors, but as with handsets there will be others like ZTE or Huawei. They make good Android handset for half the price of Motorola (ZTE Blade or Huawei U8800 for example).
You will still have to use your brain and compare product and buy something that suits your needs (I for example would only need 5 hours of battery life) but there will cheap good ones. I am pretty sure about that.
