I am leaning towards the Wilson ball machine, because it has more features than the ProLite but only a little more expensive than the Tennis Tutor that doesnt have spin. 75 mph seems like plenty for me, and the spin would be realyl useful in getting to hit different types of balls. One concern came from an earlier review that the oscillator hit too wide, and that it was hard to carry. I thought the Wilson was basically built with the same body as the Tennis Tutor? I can't justify spending 949 for a Tennis Tutor with no spin if I can get the Wilson with spin for 995!! Thanks for any input, this is a big decision!
