Ergonomic Mice

I think I'm down with a terrible design CSR standard mouse. I have looked on ebay and the alternatives are so expensive! I do not want to be paralyzed, physically and financially! Why it's worth the research that went into the design of the mouse. At the cost of hundreds of thousands of good design, and perhaps millions of dollars for research. His medications because they cost about 10 cents per pill, but then charge $ 20, because they cost a lot for the first project. The cost of doing things than they can sell. Traditional products will cost less for more.
